Overview

A shared-death experience (SDE) happens when a living person reports sensing, watching, accompanying, or helping a dying person pass into what they describe as an afterlife.^[1] The person having the SDE is fully healthy. This sets SDEs apart from near-death experiences, which happen to people who nearly die themselves.

SDEs can happen at the bedside or from a distance. They can occur during normal waking life or during sleep. Most happen at or near the moment of death. But about one quarter of documented cases occur minutes, hours, or even days before or after the measured time of death.^[1] In some cases, more than one person at the same deathbed reports an SDE. They describe overlapping but not identical experiences, as if each person is witnessing the same event from a different angle.^[1]

Stories of bystanders sharing in a dying person’s transition go back at least to the late 1800s.^[5] Early psychical researchers were interested in apparitions and crisis apparitions reported near the time of someone’s death. The Society for Psychical Research’s landmark 1886 collection Phantasms of the Living noted that a large share of spontaneous telepathy cases happened around the time of a person’s death. That was an early sign that death may be a powerful trigger for unusual experiences in bystanders. Modern SDE research builds on that history, adding systematic case collection and peer-reviewed analysis.

Key figures and research

Raymond Moody is the person most closely linked to SDEs. He is best known for coining the term “near-death experience” in his 1975 bestseller Life After Life. Moody says he first heard an SDE account from a medical professor in December 1972. He went on to collect thousands of accounts from doctors, nurses, and relatives present at deathbeds.^[3] He introduced the concept to a wide audience in the 2010 book Glimpses of Eternity, co-authored with Paul Perry. That book covered several hundred SDE reports gathered over three decades.^[6] Moody’s key argument is that healthy bystanders make SDEs stronger evidence than NDEs. As he put it: “we don’t have that option in shared-death experiences because the bystanders aren’t ill or injured, and yet they experience the same kind of things.”^[5]

William Peters is a psychotherapist and former hospice worker with the Zen Hospice Project in San Francisco. He founded the Shared Crossing Project and leads its research arm, the Shared Crossing Research Initiative (SCRI). His own SDE happened at a hospice patient’s bedside. His later work produced the first research-based system for classifying SDEs.^[7] Peters and colleagues published a major content analysis in the American Journal of Hospice and Palliative Medicine in 2021. It drew on written accounts and interviews with 107 people who together reported 164 SDEs.^[4] Peters has also presented at the American Academy of Hospice and Palliative Medicine’s Annual Conference and at the International Association for Near-Death Studies (IANDS).^[8] His book At Heaven’s Door (Simon and Schuster, 2022) brings together his clinical and research work.

A separate 2023 multicultural survey by Tressoldi and colleagues, published in the same journal, looked at SDE and after-death communication experiences across several countries. It found that hallucinatory explanations may account for many cases, especially those involving grieving relatives. But some reports, particularly those involving strangers or experiences that occurred before anyone knew a death had happened, were harder to explain that way.^[9] This growing body of peer-reviewed work marks a real shift: SDEs are moving from purely anecdotal reports toward structured scientific study.

Common features and typology

SDE reports share a recognizable pattern that closely matches classic NDEs. Common features include: leaving the body; moving toward a bright light or presence; meeting deceased people or guides; feeling an overwhelming sense of love; watching or sharing the dying person’s life review; and traveling partway into another realm before returning to normal awareness.^[10] Some bystanders also report seeing a transparent shape leave the dying person’s body at the moment of death. Others report seeing apparitions of the dying person’s deceased loved ones enter the room.^[11]

The SCRI’s 2021 content analysis identified four distinct modes of participation in an SDE. They are not mutually exclusive.^[4]

• Sensing — the most common mode. A strong intuitive knowing, often felt from a distance, that a loved one is dying or has died.
• Witnessing — perceiving unusual phenomena such as a transcendent light, apparitional figures, or a visible life-review panorama near the bed.
• Accompanying — feeling drawn out of the body and moving alongside the dying person toward a light, tunnel, or heavenly realm.
• Guiding — actively helping or directing the dying person toward the light or through a transitional space, before returning to normal awareness.

SDEs are also classified as bedside or remote, and as single-experiencer or multi-person. The multi-person type, where more than one bystander at the same death reports an SDE, is considered especially significant. Independent witnesses reporting overlapping but non-identical experiences are hard to explain through purely individual psychology alone.^[1]

Lasting effects reported after SDEs mirror those seen after NDEs: reduced fear of death, stronger belief in an afterlife, a sense of continuing bonds with the deceased, and easier grief.^[4] The SCRI research identified three major domains of SDE after-effects: changes in belief, the easing of grief, and a sense of continued connection with the deceased.^[4] These outcomes matter for palliative and bereavement care. Researchers have called for hospice teams to be trained in recognizing and supporting people who report SDEs.^[4]

Skeptical critiques

Responses and evaluation

SDE researchers accept that the evidence base has limits. But they argue the phenomenon has features that a pure grief-hallucination framework struggles to explain. The most important is simple: SDEs happen to people who are physically healthy. Standard dying-brain explanations do not apply to them. As Moody put it, states like oxygen deprivation or anaesthesia “don’t have that option” as explanations when the experiencer is a healthy bystander.^[5]

Researchers also point to a qualitative difference between SDEs and grief hallucinations. Hallucinations tend to be fragmented, incoherent, and quickly forgotten. SDE reports are described as highly organized, coherent, and recalled in fine detail years later.^[13] The multi-person SDE is the hardest case for skeptics. When two or more independent witnesses at the same deathbed report overlapping phenomena without coordinating, purely psychological explanations become strained.

The 2023 multicultural survey by Tressoldi and colleagues offered a careful conclusion. Hallucinatory origins plausibly account for many SDEs, especially those involving close relatives in acute grief. But some cases, particularly those involving strangers or experiences that occurred before anyone knew a death had happened, could not easily be ruled out as having an unusual basis.^[9] This fits the broader position in parapsychological research: collections of reported cases cannot prove a paranormal hypothesis, but they can identify a group of cases that conventional explanations struggle to cover.

Whatever their ultimate cause, SDEs have real, measurable effects. They consistently reduce fear of death, ease grief, and produce lasting changes in belief among those who report them.^[4] Researchers in palliative care have called for healthcare professionals to be trained in recognizing and responding to SDE reports in clinical settings, regardless of how those reports are ultimately interpreted.^[4] The growing publication record in peer-reviewed hospice and palliative medicine journals shows that SDEs are moving, however cautiously, from the margins of parapsychological case collection into mainstream end-of-life research.
