What Is a Near-Death Experience?

A near-death experience, or NDE, is a profound personal experience linked to death or the threat of it. Researchers describe NDEs as sharing a recognisable set of features. Most are reported after reversible clinical death, meaning the heart and breathing stopped and the person was then resuscitated, as in many cardiac arrests. Others follow serious injury or critical illness.

Most reports are positive: detachment from the body, a feeling of floating, deep serenity, warmth and security, a review of one’s life, a light, and meetings with relatives who have died. Not all of them are pleasant, though, and that minority has its own section below.

An NDE account is simply the experiencer’s own description, given after recovery. That matters. Researchers never observe the experience itself. They work with memories, recalled hours, months or decades later, and told in the words and beliefs the person already had. Because the definition of “near death” has been used loosely over the years, a group of researchers proposed guidelines in 2022 that introduced a narrower term, recalled experience of death (RED). It is meant for experiences during a loss of consciousness caused by a genuinely life-threatening event, and it excludes ordinary dreams, delirium and delusional thinking.

For readers coming from related questions about the mind’s edges, the journal’s consciousness, dreams and the mind section collects similar topics.

A Short History of Near Death Experience Accounts

Near death experience accounts are far older than the phrase itself. Near the end of Plato’s Republic is the story of a soldier from Pamphylia, killed in battle, who came back to life before his funeral pyre was lit and described what he had seen. Some modern writers read it as an early NDE.

The oldest known medical report comes from Pierre-Jean du Monchaux, an 18th-century French military doctor. He described a case in his book Anecdotes de Médecine and suggested that a rush of blood to the brain caused the experience, which makes him one of the first to propose a physical explanation. In the 19th century a few studies looked beyond single cases, including one carried out privately by members of the Church of Jesus Christ of Latter-day Saints and another in Switzerland.

The Swiss thread became the most influential. In 1892 the geologist and climber Albert Heim published a collection of first-person reports from people who had nearly died: workers who fell from scaffolding, wounded soldiers, climbers who survived falls, and people pulled from near drownings. It was the first time the phenomenon was described as a clinical syndrome. In the same decade, the French psychologist Victor Egger proposed a French term meaning “experience of imminent death,” after philosophers and psychologists debated climbers’ stories of seeing their whole lives flash past as they fell.

The 20th century brought more systematic work:

  • 1968: Celia Green analysed 400 first-hand accounts of out-of-body experiences, the first attempt to sort them into types.
  • 1969: Elisabeth Kübler-Ross, a pioneer in the study of dying, published On Death and Dying.
  • 1972: John C. Lilly used the phrase “near-death experience.”
  • 1975: Psychiatrist Raymond Moody popularised the term as an umbrella for out-of-body experiences, the life review, the tunnel, the light and the border.
  • 1980: Kenneth Ring reorganised Moody’s observations into a five-stage sequence.
  • 1983: Bruce Greyson introduced a standard scale researchers could use to identify NDEs.

By 2005, about 95 percent of the world’s cultures were known to have mentioned something like an NDE.

What Do Near Death Experience Accounts Have in Common?

Moody based his 1975 work on around 150 people who said they had had an NDE, and studied about 50 of them closely. He identified fifteen recurring elements, while stressing that no single account contains all of them. Grouped loosely, they fall into a few clusters:

  • Crossing over: hearing that one has died, pain giving way to calm, a strange noise or unearthly music, and movement through darkness or a tunnel.
  • Being elsewhere: seeing one’s body from outside, meeting others, and encountering a being made of light.
  • Judgement and limits: a panoramic review of one’s life and a boundary that cannot be crossed if one is to return.
  • Afterward: difficulty putting it into words, a changed view of death, and lasting effects on how one lives.

Ring simplified the experience into a sequence: peace, separation from the body, entering darkness, seeing the light, and passing through the light into another realm, followed by resuscitation. The 2022 guidelines went the other way and listed more than fifty detailed themes. These include unexpected mental clarity, a sense of being joined to the body by an energetic thread, a life review felt from other people’s points of view, a feeling of coming “home,” communication by thought alone, and a reluctant obligation to return.

How often each element appears

One author who pooled studies across different patient groups reported these approximate frequencies:

Reported elementShare of experiencers
Peace, well-being or blissabout 56%
Awareness of being deadabout 50%
Meeting deceased loved ones or religious figuresabout 32%
Tunnel or entering darknessabout 31%
Out-of-body experienceabout 24%

The famous tunnel, in other words, shows up in fewer than a third of reports. The authors of the 2022 guidelines dispute this kind of pooling. They argue that “classic” NDEs among people who were actually dying differ sharply from experiences grouped with them by mistake, and that the two share little beyond surface features such as peace or religious imagery.

How many people report them

A 2011 paper in the Annals of the New York Academy of Sciences estimated that about nine million people in the United States have reported an NDE, mostly after serious injury to the body or brain. Across nine prospective studies of critically ill patients (studies that follow patients forward from the event rather than collecting stories later), about 17 percent reported one.

Are NDEs Real? The Explanations Proposed

Nobody serious doubts that people have these experiences. The argument is over what produces them, and it is one of the longest-running debates in the study of consciousness.

The brain-based case

One leading neuroscience hypothesis holds that an NDE is a subjective event caused by disturbed multisensory integration: under life-threatening stress, the brain stops properly combining signals from the body. That breakdown could produce floating, the sense of viewing oneself from outside, and a distorted sense of time. Du Monchaux’s 18th-century theory about blood flow to the brain was an early version of the same idea, and changes in brain chemistry and oxygen during crisis are often suggested too.

Skeptics add several points. Accounts are reconstructed from memory, sometimes long afterward, and memory is easily shaped by retelling and expectation (the journal’s piece on the Berenstain Bears Mandela Effect shows how confidently people can remember things that never were). Drugs such as ketamine and DMT can produce experiences that feel NDE-like. In one series, 22 percent of experiences labelled as NDEs happened under general anesthesia rather than near death. And frightening hospital episodes may be ICU delirium, which is well documented in critically ill patients.

The case for something stranger

The strongest argument on the other side is a paradox the 2022 guidelines highlight. As the body approaches death, mental clarity should fade, and in extreme cases detectable brain function disappears. Yet the most typical near death experience accounts describe the opposite: coherent, vivid, meaningful experiences with a lucid life review, arising when the brain should be least able to produce them.

The same guidelines also say drug-induced “NDE-like” states are not quite the same thing. They tend to include distorted body sensations, a self-centred perspective, and imagery such as elves, celebrities, geometric patterns, aliens or neon scenes, none of which are typical of recalled death experiences. Supporters also point to experiencers who say they watched their own resuscitation from above. Some of these cases are held up online as medically documented, and they remain heavily argued over.

Still openHow lucid experiences can occur when brain function is severely impaired, and whether any perception outside the body can be verified.

Culture, Religion and Who Appears in the Light

The bones of the experience recur widely, but the details tend to follow the experiencer’s culture, philosophy and religion. In the United States, where 46 percent of people say they believe in guardian angels, the light is often identified as angels or deceased relatives, or is left unnamed. Hindu experiencers have described the figures they met as messengers of the god of death.

Researchers suggest that cultural background shapes some of what is experienced but shapes the later interpretation even more. A person may meet “a presence” and only later, when trying to put it into words, call it Jesus, an ancestor or a guide. That helps explain why no reliable percentage exists for any single religious figure. The 32 percent figure above counts deceased relatives and religious figures together.

The effect on belief is also less predictable than often assumed. People who have had NDEs tend to become more spiritual, but not necessarily more religious. Experiencers who describe leaving the body sometimes connect it with practices covered in the journal’s guide to astral projection, although researchers treat spontaneous NDEs and deliberate out-of-body practice as separate subjects.

Distressing Near-Death Experiences

Not every account is serene. After Moody’s work became widely known, reports appeared of experiences in which people felt persecuted, trapped or terrified. These were labelled negative or “hellish” NDEs and have since become a familiar part of popular stories of near death experience.

Researchers are divided on them. Some treat distressing NDEs as a real, under-reported category. The authors of the 2022 guidelines argue that most such reports lack the narrative structure, transcendent quality and long-term transformation of classic NDEs. In their view, many are better explained as ICU delirium and delusions, which can arise from metabolic disturbances, withdrawal and other conditions in critically ill patients. They also note that the original category was never given a formal definition.

A separate and sensitive strand concerns people who survive suicide attempts. Some describe intense emotional pain that felt like a torment of their own making. These accounts deserve care rather than sensational retelling. Anyone in that kind of pain can reach a crisis line or a medical professional at any time.

Even positive experiences can leave difficulties behind. Greyson has described cases where the changes in attitude and behaviour that follow an NDE led to social and spiritual struggles, such as feeling isolated from family or unable to fit the experience into ordinary life.

How to Read Near Death Experience Accounts With a Clear Eye

Collections of near death experience accounts range from peer-reviewed case reports to anonymous posts. Some online registries publish submissions anonymously with light edits to protect identities, and openly say the people involved were never interviewed. That does not make those stories false, but it does make them a different kind of evidence. A practical way to weigh any single near-death experience testimony:

  1. Check the medical context. Was the person in cardiac arrest or critically ill, or asleep, anesthetised or simply frightened? The 2022 guidelines put a real threat to life at the centre of the definition.
  2. Note when it was recorded. An account given days after resuscitation carries different weight from one first written down decades later.
  3. Ask who collected it. A prospective hospital study, a researcher’s interview, a book and an anonymous registry entry each have different strengths and weaknesses.
  4. Look for checkable details. If someone says they saw something from outside their body, could it be confirmed, and was it written down before anyone tried to confirm it?
  5. Separate experience from interpretation. “A loving light” is the experience; “I met God” is how one person understood it.
  6. Be wary of loose scoring. Greyson’s scale uses broad terms such as “unearthly place,” “joy” and “harmony.” Critics note that someone describing a peaceful holiday and some reflection on their life could tick several boxes, which is how false positives arise.

A worked example: Heim’s falling climbers

Apply the checklist to Albert Heim’s 1892 reports. The threat was real: falls, near drownings and battlefield wounds. The accounts were first-hand. But most of these people did not suffer cardiac arrest, and the experience they shared, a rapid life review during the fall, happened while the brain was presumably still working. Under the strict 2022 definition, some might not count as recalled experiences of death at all, yet they gave the field its first clinical description. A single collection can therefore be historically essential and still leave the hardest question untouched.

Common mistakes

  • Treating the tunnel and the light as universal when most accounts lack a tunnel.
  • Assuming cross-cultural similarity proves a shared afterlife, or that cultural variation proves the opposite.
  • Counting anesthesia dreams, drug experiences or delirium as NDEs without checking the circumstances.
  • Treating a vivid, sincere story as verified perception, or dismissing it as a lie, when neither follows.

Life After the Experience

Whatever causes them, NDEs often leave a lasting mark. Ring found a consistent pattern of changes in experiencers: greater appreciation for life, higher self-esteem, more compassion, less interest in material wealth, a stronger sense of purpose, a desire to learn, deeper spirituality, more concern for the planet, a feeling of being more intuitive, and much less fear of death. Many said they had seen an afterlife.

For people close to someone who has just come back from one, Moody summed up a sensible response in five words: ask, listen, validate, educate and refer. Experiencers often say the hardest part was not the experience itself but finding someone willing to hear it without either worshipping or dismissing it.

That is perhaps why near death experience accounts keep drawing readers. They sit where medicine, memory, belief and the unanswered question of consciousness meet. Related territory is covered in the journal’s look at remote viewing, another case of claimed perception beyond the senses, and in its paranormal accounts section. For long-form conversations about the unexplained, the Troubled Minds Vault holds the radio show’s back catalog. More articles are listed in the full journal.

Questions and answers

What is the most common NDE experience?

A deep sense of peace is the most widely reported element. In one review that pooled studies, about 56 percent of experiencers described peace, painlessness or bliss, and about half said they were aware of being dead. Tunnels or darkness, meeting deceased loved ones or religious figures, and out-of-body perception were each reported by roughly a quarter to a third. Researchers disagree about whether pooling different patient groups this way is valid.

Are NDEs real or fake?

The experiences are real in the sense that people genuinely have them and report them consistently across eras and cultures. The open question is what causes them. Neuroscience points to a brain under extreme stress, with disrupted integration of bodily senses. Others argue that lucid, coherent experiences during severe loss of brain function suggest consciousness may not depend entirely on the brain. Neither side has settled the question.

What is an NDE account?

An NDE account is a person's own description, given after recovery, of what they experienced while close to death or during reversible clinical death, such as a cardiac arrest followed by resuscitation. Accounts are collected in research interviews, hospital studies, books and anonymous online registries. Because they are recalled after the event, researchers look closely at the medical context and at when and how each account was recorded.

What percent of NDEs involve seeing Jesus?

No reliable figure exists for Jesus specifically. One review found that about 32 percent of experiencers reported meeting deceased loved ones or religious figures, counted together. Who appears tends to follow the person's culture and faith. In the United States the light is often described as angels, relatives or an unnamed presence, while Hindu experiencers have described messengers of the god of death.

Are there negative or frightening near-death experiences?

Yes. Some people report frightening or distressing experiences, and these accounts have been called negative or hellish NDEs. Researchers disagree about them. Some treat them as a genuine category of near-death experience, while the authors of 2022 research guidelines argue that many are better explained as ICU delirium, which is well documented in critically ill patients and can produce persecutory, dreamlike episodes.
