1. Introduction
Version followed: Raymond A. Moody Jr.'s "facilitated apparitions" procedure as he reported it in Journal of Near-Death Studies 11(2), 1992. The popular book Reunions (Moody & Perry, 1993) describes the same work for general readers but is not drawn on here. Research variants (Hastings et al., 2002; Schlitz et al., VR psychomanteum) are noted where they differ. [source: Moody 1992; Greyson 1996 review of Reunions; Psi Encyclopedia]
What it is. Moody modelled his "psychomanteum" on the oracles of the dead of ancient Greece. A bereaved adult spends a day remembering a chosen deceased person with a guide. At dusk they sit alone in a darkened, curtained chamber, gazing into a large mirror angled so that it shows no reflection of them, only dim depth. Afterwards there is an extended processing session. [source: Moody 1992; Moody 1994 abstract] A date of 1993 is sometimes given because of Reunions. Moody's first published report is from 1992, and he ran the work at his "Theater of the Mind" in Alabama from about 1990. [source: Psi Encyclopedia; Greyson 1996]
Status. This is not a manualised psychotherapy. It is an experiential procedure, and its originator described it as "not a scientific study." Moody suggested that therapeutic techniques for grief "might be derived" from it. [source: Moody 1992] It has no recognised place in grief treatment guidelines. The evidence-based treatment for prolonged grief disorder is Complicated Grief Treatment, a 16-session manualised therapy. [source: Focus 2021 review] Any use in therapy described below as a grief intervention is therefore a clinical adaptation [synthesis]. No licensing or regulatory framework governs it [uncertain: none found].
How change is thought to happen. Moody describes the gazing as an altered state, which he relates to hypnagogia, set in an environment and preparation that focus memory and longing on one person. Many participants reported perceiving the deceased, often very vividly, and described this mainly as "healing" of the relationship. Others said their grief eased or resolved. [source: Moody 1992] Moody said the approach "makes no claims whatsoever" about what these experiences are. Participants were unanimous that the events felt real, and Moody personally held that his grandmother had been present. That is his and the participants' interpretation, not an established fact. [source: Moody 1992] In Hastings et al. (2002), grief improved significantly whether or not a participant reported any contact experience. This suggests the guided remembering, the ritual frame and the processing may matter as much as any anomalous experience. [source: Psychology Today 2023 summary of Hastings et al. 2002; the detail is uncertain]
2. Framework
Moody's procedure is a single extended day, not a course of sessions. The phases below are his. The clinical "before" and "after" phases (0 and 5) are [synthesis]. [source: Moody 1992 unless marked]
| Phase | Goal | Format / timing | Move on when |
|---|---|---|---|
| 0. Clinical assessment and decision [synthesis] | Establish grief type and risk, contraindications, motivation and beliefs; obtain informed consent | 1–2 ordinary sessions before the day | Screening passed (Section 3, item 2); consent given; the client accepts that nothing may happen |
| 1. Arrival and motivational walk | Explore why the person wants this; take away pressure to "perform" | Morning (Moody: arrival 10 a.m.; a 3–4 mile countryside walk with the guide) | The motivation is clear, and the client has heard that an apparition is not guaranteed |
| 2. Light meal | Keep the person comfortable without heaviness | Midday (Moody: soups, salad, fruit, juices) | — |
| 3. Remembrance conversation with mementos | Bring the deceased vividly to mind: personality, appearance, habits, the relationship, significant memories | Afternoon, extended; the client brings mementos, which are handled and discussed | The person feels absorbed in memory and settled rather than flooded (judgement call) [synthesis for the criterion] |
| 4a. Relaxation (optional) | Deepen relaxation before gazing | About 45 min in a recliner with music; used with about two-thirds of Moody's subjects | Relaxed, alert enough to proceed |
| 4b. Gazing in the chamber | Unstructured gazing with an intention to meet the deceased | Around dusk; no time limit; no watch; an attendant waits in the next room. Later research versions used about 45 min [source: Psychology Today 2023] | The client chooses to come out |
| 4c. Extended processing session | Discuss the experience, express feelings, reach "closure" | Straight after gazing; length not stated by Moody | The client is grounded and oriented and has a follow-up plan |
| 5. Follow-up and integration [synthesis] | Process any delayed experiences; fold meaning into ongoing grief work; re-screen risk | 1–3 sessions over the following weeks | Integrated, or referred on |
Moody's sample: 25 fully guided subjects. 12 reported apparitions, plus 4 who had a briefer preparation (16 in all). 6 of the 16 reported communication. 13 reported a strong sense of presence, and some saw a different deceased person from the one they had chosen. Moody stressed that these figures were only a rough index. [source: Moody 1992] The Psi Encyclopedia, summarising Reunions (about 300 people), adds that about a quarter met someone other than the intended person and about a quarter had an apparition afterwards, usually within 24 hours. [source: Psi Encyclopedia]
3. Guiding principles
- No guarantee, no pressure. Tell the client plainly that nothing may happen and that nothing is expected of them. Practically: say this at consent, on the day and again in processing; a "blank" session is not failure. [source: Moody 1992; Hastings result via Psychology Today 2023]
- Select for stability. Moody chose mature, emotionally stable, inquisitive, articulate adults. He excluded people with known emotional or mental disorders and people with occult ideologies. Greyson stressed selecting for stability "rather than their psychic ability." Practically: do not offer it to people in acute crisis or with the vulnerabilities listed in Section 5.1. [source: Moody 1992; Greyson 1996]
- Never alone. Moody advises against attempting it alone: there must be a competent, grounded support person and time for processing. Greyson warns that improvised home versions without preparation and debriefing risk distressing "bad trips." Practically: the clinician, or a trained colleague, stays nearby throughout and runs the debrief; do not recommend DIY home versions. [source: Moody 1992; Greyson 1996]
- Stay attuned to grief. Moody stresses "remaining attuned to the relevance of grief." Practically: grief work is the purpose, the phenomena are secondary, and the clinician's attention stays on the relationship and the loss, not on producing visions. [source: Moody 1992]
- Agnostic about the experience. Moody's approach makes no claims about what the experiences are; participants judge for themselves. He also cautioned against using the procedure as evidence of survival after death. Practically: neither confirm nor debunk; explore what the experience means to the client within their own worldview. [source: Moody 1992]
- Setting matters, but adapt it. Moody notes the setting is important and that others should not copy his facility exactly. Practically: build a safe, quiet, dark, private space suited to your context and the client's culture. [source: Moody 1992]
- Preparation is the working core. The long remembrance conversation and the handling of mementos come before any gazing. Practically: even if the chamber is never used, the remembrance work is a grief intervention in its own right [synthesis]. [source: Moody 1992]
- Expect strong and unexpected feelings. Encounters "stir up strong feelings" and can raise awkward family questions. Practically: leave ample processing time and a follow-up appointment. [source: Moody 1992]
- Respect beliefs and religious authority. Some religious traditions have historically discouraged mirror-gazing or contact with the dead. Practically: ask about the client's faith and, if they wish, involve their own religious adviser; do not proceed against their convictions. [source: Psi Encyclopedia for the historical discouragement; the clinical step is synthesis]
- Grief diagnosis comes first. Prolonged grief disorder carries raised suicide risk and has an evidence-based treatment. Practically: screen for PGD and suicidality before offering this, and refer or treat PGD with Complicated Grief Treatment rather than offering the psychomanteum instead of it. [source: Focus 2021 review; the decision rule is synthesis]
4. Intervention inventory
Items 4.3 to 4.10 are Moody's components, in his order [source: Moody 1992]. Items 4.1, 4.2 and 4.11 are clinical scaffolding: Moody gives the selection criteria, and the screening content is mainly [synthesis]. Item 4.12 covers research variants. All example language is illustrative.
4.1 Screening and assessment interview
- Purpose: decide whether the procedure is suitable, safe and wanted. Moody selected for maturity, emotional stability, curiosity and articulateness, and excluded people with known emotional or mental disorders and those holding occult ideologies. In later work he asked for people who had no unresolved issues with the deceased, which some volunteers objected to. [source: Moody 1992]
- Steps:
- Take a bereavement history: who died, when, how (expected, sudden, violent, suicide), the nature of the relationship, and current supports. [synthesis]
- Screen for prolonged grief disorder. DSM-5-TR requires at least 12 months since the death (6 months for children and adolescents), yearning or preoccupation most days, at least 3 of 8 accessory symptoms for the last month, and impairment beyond cultural norms. ICD-11 uses a minimum of 6 months. Brief tools named in the literature are the Brief Grief Questionnaire, the PG-13, the Inventory of Complicated Grief and the SCI-CG; use licensed versions and do not improvise items. [source: Focus 2021 review]
- Assess suicide risk in every bereaved client, using your service's standard structured approach. Explicitly ask about wishes to die or to "join" the deceased, which the Focus review lists as a PGD feature. Risk is higher in PGD even after accounting for depression and PTSD, and higher again after a suicide death. Cover current and lifetime psychiatric history, mental state, and medical and treatment history. [source: Focus 2021 review]
- Screen for the exclusions and cautions in 5.1: psychosis, bipolar disorder, dissociative disorders, schizotypy, unstabilised PTSD or traumatic bereavement, current substance misuse, and acute crisis. [Moody 1992 for "known emotional or mental disorders"; the specific list is synthesis]
- Explore beliefs: the client's religious tradition and its view of contact with the dead, their prior perceptions of the deceased, and their fears (for example, being haunted, or a reproachful encounter). [synthesis]
- Decide. If PGD or significant risk is present, treat or refer first (Section 5.2). If the client is suitable, proceed to consent.
- Example language (illustrative): "Before we consider this, I'd like to understand how your grief has been, including whether you've had any thoughts of wanting to die or to be with her."
- Watch for: a client who hopes the session will "fix" the grief or confirm survival; yearning for reunion combined with hopelessness (a risk flag); pressure from family members.
4.2 Informed consent and expectation-setting
- Purpose: an informed, free choice with no performance pressure. [source: Moody 1992 for the "no guarantee, no pressure" message; the consent content is synthesis]
- Steps: (1) Explain the procedure and its origin as an experiential method with no established treatment status. (2) Explain possible experiences: nothing at all; lights, mist or colours; a sense of presence; a figure, sometimes a different person from the one chosen; experiences later at home. [source: Moody 1992; Psi Encyclopedia] (3) Explain the risks: strong emotion, unsettling family implications, transient depersonalisation or derealisation, and frightening imagery. [source: Moody 1992; Caputo 2019; Greyson 1996] (4) Explain that the client can stop at any time, how to call the attendant, and the aftercare plan. (5) Agree a stance on interpretation: the clinician will not tell them what the experience was. (6) Document consent.
- Example language (illustrative): "Some people see or sense something, many don't, and both are fine. People who saw nothing in one study still felt their grief eased. You can come out whenever you want."
- Watch for: fixed expectations of a guaranteed reunion, or consent given to please someone else.
4.3 Motivational walk
- Purpose: explore why the person wants to do this, ease tension and lift any sense of obligation. Moody walked 3 to 4 miles through countryside with each subject, discussed their motivation, and told them an apparition was not guaranteed. [source: Moody 1992]
- Steps: walk side by side at an easy pace, or offer a seated alternative for mobility limits [synthesis]. Ask open questions about what they hope for, what they fear, and what they would want to say. Repeat the "no guarantee" message.
- Example language (illustrative): "What would it mean to you if something happened today? And if nothing did?"
- Watch for: unfinished business such as guilt, anger or unsaid words. Note it for the remembrance work and the debrief.
4.4 Remembrance conversation
- Purpose: bring the deceased vividly and personally to mind. [source: Moody 1992]
- Steps: in an extended, unhurried afternoon conversation, cover the person's personality, appearance, habits and mannerisms, the story of the relationship, and the memories that matter most. Follow the client's lead and let feeling come. [source: Moody 1992 for the content; the pacing is synthesis]
- Example language (illustrative): "Tell me what he was like on an ordinary Sunday. How did he laugh? What did he call you?"
- Watch for: flooding (sobbing that does not settle, panic, dissociation). Slow down, ground the client, and consider stopping before the gazing (Section 5.4). Signs it is working: warmth, absorption in memory, and grief expressed with some sense of connection.
4.5 Memento handling
- Purpose: use concrete objects to anchor memory. Subjects brought mementos, and subject and guide handled and discussed them together. [source: Moody 1992] (Moody himself spent hours with old photographs in his own preparation [source: Psi Encyclopedia].)
- Steps: before the day, ask the client to bring a few objects or photographs. Hold or look at each one together and invite the story behind it. The client may keep one item with them in the chamber [uncertain: not stated by Moody; synthesis option].
- Example language (illustrative): "Would you show me this watch? Where did he wear it?"
- Watch for: an object that carries painful associations, such as the circumstances of the death. Ask before using it.
4.6 Pre-gazing relaxation (optional)
- Purpose: deepen relaxation. About two-thirds of Moody's subjects spent around 45 minutes in a recliner listening to music played through bone conduction. Hypnosis was not part of the procedure. [source: Moody 1992]
- Steps: offer a quiet, comfortable recliner and calm music (any playback is fine; bone conduction was Moody's equipment, not a requirement) [synthesis for the equipment]. Simple breath awareness can be added [synthesis].
- Example language (illustrative): "Let the music carry you for a while; there's nothing you need to do."
- Watch for: drowsiness that tips into sleep; anxiety that rises when the client is less active (ground them and check in).
4.7 Preparing the chamber
- Purpose: a dark, quiet, enclosed visual field in which the mirror shows depth but not the sitter. [source: Moody 1992]
- Steps (Moody's set-up, to adapt, not copy): a large mirror (his was about 4 ft high by 3.5 ft wide) hung with its lower edge a little below eye level for a low seat; a comfortable low chair about 3 ft in front of it, tilted back slightly so the sitter cannot see their own reflection; a small, dim lamp (25 W stained glass) directly behind the chair; black velvet curtaining from floor to ceiling around the sitter and below the mirror; all other light excluded. [source: Moody 1992] Later descriptions mention an all-black small room, a footrest, a mirror angled high on the wall and nightlight-level light. [source: Psychology Today 2023] Add: a call bell or other agreed signal, a clear exit route, a nearby light switch, and a fire-safe lamp [synthesis].
- Watch for: reflections of the sitter (re-angle the mirror); claustrophobia; trip hazards in the dark [synthesis].
4.8 The gazing session
- Purpose: unstructured gazing with an intention to meet the deceased. [source: Moody 1992]
- Steps: (1) Around dusk, seat the client, switch on the lamp and remove all other light. [source: Moody 1992] (2) Instruct them to gaze deeply into the mirror, relax and wait for the person to appear. [source: Moody 1992] Research versions describe entering "with a clear mind" and an intention to make contact. [source: Psychology Today 2023] (3) No time limit and no watch; the client comes out when they choose. [source: Moody 1992] In a clinic, agree a soft maximum, for example a check-in at 45 to 60 minutes [synthesis; 45 min is the research figure]. (4) Remind them of the signal and that they may stop at any time [synthesis].
- Example language (illustrative): "Look deeply into the mirror, relax, and simply wait. Whatever happens, or doesn't, is fine. I'm next door; ring if you need me."
- Watch for: as reported by participants: mist or smoke, colours, geometric lights, a sense of presence, full figures, voices, figures seeming to leave the mirror, being touched or embraced. [source: Moody 1992; Psi Encyclopedia] Caputo's experimental gazing studies report strange or distorted faces, depersonalisation and derealisation. [source: Caputo 2019] These are reports and perceptions; the clinician does not present them as real contact with the dead.
4.9 Attendant role during the session
- Purpose: safety and containment. In Moody's work an attendant sat in the next room throughout, ready to help. [source: Moody 1992]
- Steps: stay within earshot, do not interrupt unless signalled or worried, and keep the debrief space ready. If called, turn the light up gradually and orient the client to time, place and your presence. [synthesis for these details]
- Watch for: sounds of distress, prolonged silence well past the agreed check-in time [synthesis].
4.10 Extended processing session
- Purpose: discuss the experience, let the client express their feelings, and reach closure. Moody called this an "extended processing session" but did not state its length. [source: Moody 1992] Greyson's review treats a guide who prepares and debriefs as essential. [source: Greyson 1996]
- Steps [structure is synthesis]: (1) Ground first: gradual light, a warm drink, feet on the floor, orientation. (2) Invite an open account in the client's own words, without interpreting. (3) Explore what it felt like, what it meant, and what was said or left unsaid. (4) If nothing happened, explore what the day of remembering brought up. In Hastings et al. (2002), people with no experience also improved [source: Psychology Today 2023]. (5) If the figure was unexpected or the encounter was painful, explore it as material about the relationship, not as a verdict. (6) Check mental state and safety before the client leaves, including suicidal thoughts after the encounter (for example, a heightened wish to rejoin the person). (7) Warn the client that experiences may come later, at home or elsewhere, often within 24 hours [source: Moody 1992; Psi Encyclopedia], and agree what to do if one does. (8) Book follow-up, and make sure they do not drive home if they are not fully alert [synthesis].
- Example language (illustrative): "Take your time. Tell me what happened, in whatever order it comes." / "What do you make of it yourself?"
- Watch for: lingering depersonalisation (it should fade; in Caputo's gazing work, earlier effects "completely dissipated within 15 minutes" [source: Caputo 2019]); agitation, elation or sleeplessness, which may signal hypomania in a vulnerable person; fear of being haunted; family dilemmas raised by the experience (Moody described a subject unsure whether to tell his sister). [source: Moody 1992]
4.11 Follow-up and integration [synthesis, building on Moody's processing]
- Purpose: fold the experience and the remembrance into ongoing grief work, and re-check risk.
- Steps: (1) Hold sessions at about 1 week and 4 weeks. (2) Process any delayed experiences. (3) Help the client place the experience within their own worldview, whether religious, secular or uncertain, without the clinician ruling on whether it was "real". Continuing-bonds ideas (Klass, Silverman & Nickman) are an established frame for this [uncertain: cited in the Psychology Today reference list]. (4) Re-administer the grief measure used at baseline, and repeat the suicide check. (5) Discourage repeated DIY home sessions. If a lasting ritual of connection is wanted, help design a safer one, such as a letter, a visit to the grave or a memory object. [synthesis; Greyson 1996 for the DIY concern]
- Example language (illustrative): "How has that evening stayed with you this week?"
- Watch for: the client becoming preoccupied with repeating the contact (yearning feeding PGD); a new conviction of being followed or haunted; withdrawal from the living.
4.12 Research variants (not established clinical procedures)
- Hastings et al. (2002): a pilot with 5 people, then 27 participants. The procedure ran from recalling the deceased, to a gazing session focused on them, to sharing afterwards. It used pre- and post-session questionnaires, the Myers-Briggs and the Tellegen Absorption Scale, and reported improvement in grief, unresolved feelings, guilt and the felt need to communicate, whether or not contact was experienced. A later study of 100 participants is cited for similar results. [source: Psychology Today 2023; Signori page (non-expert secondary); the detail is uncertain]
- Guided induction and a VR psychomanteum (Schlitz and colleagues, Sofia University / IONS, funded by the Bial Foundation): a recorded induction intended to raise expectations of contact, compared across a physical sensory-deprivation chamber and a virtual-reality version, measuring depth of experience, change in grief and absorption. Results were preliminary. [source: IONS page] For a clinician, note that an induction which raises expectation is a deliberate suggestion effect, and consent should say so [synthesis].
- Watch for: none of these variants has published safety procedures in the sources [uncertain].
5. Handling problems
5.1 Contraindications and screening (named in sources vs added)
- Named in sources: known emotional or mental disorders; occult ideologies (Moody's exclusion); lack of emotional stability; attempting it alone; DIY or home use without preparation and debriefing. [source: Moody 1992; Greyson 1996]
- Added by me [synthesis], with partial source support where marked:
- History of psychosis or bipolar disorder: the method deliberately induces perceptual anomalies.
- High schizotypy or psychosis-proneness: strange-face illusions are linked to schizotypy in adolescents [source: Caputo 2019 citing earlier work; Fonseca-Pedrero et al. 2015, Schizophrenia Bulletin].
- Dissociative disorders or prominent depersonalisation or derealisation: gazing-induced illusions correlate with both [source: Caputo 2019, healthy sample].
- Prolonged grief disorder, current suicidal ideation, or a wish to join the deceased: refer for or provide evidence-based treatment first [source: Focus 2021 review for the risk].
- Traumatic bereavement (violent death, suicide, finding the body) or unstabilised PTSD.
- Very recent bereavement [uncertain: no threshold was found in the sources].
- Current substance intoxication or misuse.
- Children and adolescents (Moody's subjects were adults aged 22 to 74 [source: Moody 1992]).
- Religious objection.
- Severe claustrophobia or fear of the dark.
- Medical conditions that make sitting alone in the dark for a long time unsafe.
5.2 Prolonged grief disorder and suicide risk
- If DSM-5-TR or ICD-11 PGD criteria appear to be met, offer or refer for Complicated Grief Treatment (16 sessions, combining attachment theory and CBT) or grief-specific CBT. Treat comorbid depression, PTSD and insomnia. [source: Focus 2021 review] The psychomanteum is not a substitute [synthesis].
- Suicide risk: assess at screening, at the end of the processing session and at follow-up. If risk is present, follow your service's standard risk assessment and safety planning, which includes lethal-means counselling (safe storage or removal of means), involving supports and arranging urgent review. Postpone or cancel the procedure. [synthesis consistent with standard practice; Focus 2021 for the elevated risk]
- Specific flag: after a vivid "reunion", some clients may idealise death or feel pulled towards the deceased. Ask directly. [synthesis]
5.3 Documented adverse and difficult effects, and responses
- Strong feelings, or awkward family implications [source: Moody 1992]: give the processing session ample time; discuss whether, how and with whom to share the experience; offer follow-up.
- An unexpected person appears (about a quarter of people, per the Psi Encyclopedia summary): explore that relationship. This may raise unacknowledged grief or conflict.
- Experiences after the session (about a quarter within 24 hours, per the Psi Encyclopedia; 3 subjects in Moody 1992): forewarn the client; give them a contact route; normalise this as reported by participants, without asserting that it is contact.
- Depersonalisation, derealisation, or strange or distorted faces [source: Caputo 2019]: stop if this is distressing; raise the light; ground the client (name five objects, feel the feet, sip a cold drink); in Caputo's work the effect was transient. If it persists beyond the session, assess and refer [synthesis].
- Frightening or reproachful imagery, a "bad trip" [source: Greyson 1996 for the risk; the response is synthesis]: stop, orient, contain; process it as grief material (guilt, anger); do not repeat the procedure.
- Hypomanic or psychotic signs afterwards (sleeplessness, grandiosity, a fixed belief in continuing messages) [synthesis]: arrange same-day psychiatric assessment.
- The documentation gap: Moody reports no untoward reactions, but he did not measure them systematically, and no study opened reports formal adverse-event monitoring [uncertain].
5.4 Stuck, resistant or non-adherent clients
- Nothing happens [source: Hastings result via Psychology Today 2023]: reframe that the remembrance itself is the work; do not offer repeated sittings to "get a result" [synthesis].
- Can't settle, or keeps checking the time: remove the watch (Moody's instruction); lengthen the relaxation period; or stop and use the remembrance work alone [synthesis].
- Ambivalence or fear on the day: honour the client's choice to stop at any point; the walk and the remembrance stand on their own [synthesis].
- Flooding during remembrance: pause, ground, shorten the session, and do not proceed to gazing that day [synthesis].
- Wants to do it at home or repeatedly: explain Greyson's and Moody's cautions about doing it alone or without a support person; offer safer rituals of connection [source: Moody 1992; Greyson 1996].
5.5 Ruptures and worldview conflicts [synthesis]
- Client asks "Was it really her?": reflect Moody's own stance that the approach makes no claims [source: Moody 1992], and explore what the client believes. Do not affirm or debunk.
- Client feels judged as "irrational", or feels the therapist is pushing a spiritual agenda: name the agnostic frame and return to the grief goals.
- Family or faith-community disapproval: respect the authority of the client's tradition; involve their religious adviser if the client wishes.
- Professional-boundary risk: document the rationale, the consent and the screening; check your professional body's and insurer's position before offering an unestablished procedure [uncertain: no regulatory guidance found].
