The near-death experience occupies a peculiar and generative position within the depth-psychology corpus: it serves simultaneously as phenomenological datum, neurobiological hypothesis, and threshold symbol for the dissolution and reconstitution of selfhood. Rick Strassman advances the most sustained neurochemical thesis, arguing that endogenous DMT released by the pineal gland at the moment of biological crisis is not an epiphenomenal side effect but the very mechanism by which consciousness exits the body — a functional, purposive event. Iain McGilchrist attends to the phenomenology proper, cataloguing the signature features of the NDE — panoramic life review, accelerated cognition, unconditional love, and durable value-transformation — as evidence that consciousness is not reducible to brain function. Irvin Yalom approaches the near-death encounter from an existential-therapeutic standpoint, treating it as a boundary situation that shatters defensive denial and catalyzes authentic reorientation toward living. Dacher Keltner situates the NDE within the broader science of awe, noting its structural kinship with nekyia narratives across traditions. Across these positions, a central tension persists: whether the near-death experience is best understood as a biochemical artifact, a genuine ontological crossing, or a psychotherapeutic catalyst. All agree, however, that proximity to death transforms the experiencer in ways that ordinary consciousness rarely accomplishes.
Near-death brain products are psychedelic because those are the properties consciousness requires at that time. Psychedelic compounds released near death mediate consciousness exiting the body. This is their function and this is what they do.
Strassman argues that the psychedelic character of near-death brain chemistry is not incidental but teleologically necessary — DMT is the mechanism by which consciousness departs the body.

Near-death brain products are psychedelic because those are the properties consciousness requires at that time. Psychedelic compounds released near death mediate consciousness exiting the body. This is their function and this is what they do.
Strassman's core biological thesis holds that endogenous psychedelics released near death serve a purposive function in facilitating the departure of consciousness from the body.

Near death experiencers report overwhelmingly that they're 'more spiritual' after the experience, they have more compassion for others, and a greater desire to help others, a greater appreciation for life, and a stronger sense of meaning or purpose in life.
McGilchrist marshals clinical and psychiatric evidence to show that near-death experiences produce durable, measurable transformations in values, spirituality, and mental functioning.

An analysis of their medical records shows that mental functioning is significantly better in those people who come closest to death. Many NDErs experience a panoramic life review, not just visual images, but elaborate events, sometimes the entirety of that person's life.
McGilchrist presents empirical findings suggesting that proximity to death enhances rather than diminishes mental functioning, challenging materialist assumptions about the brain-consciousness relationship.

The near-death encounter spells what seems to be the end of those concerns by simulating or foretelling what it's like once our individual bodies fall away. Near-death experiences seem to have the greatest impact on those who take the next step within that mysterious experience—the leap to a mystical level of awareness.
Strassman positions the near-death encounter as a gateway from personal psychological resolution to transpersonal mystical experience, with the leap to mystical awareness constituting its highest yield.

Near-death experiences seem to have the greatest impact on those who take the next step within that mysterious experience—the leap to a mystical level of awareness.
Strassman identifies the transition from near-death phenomenology to mystical consciousness as the most psychologically and spiritually transformative trajectory within DMT-induced experience.

Noyes studied two hundred patients who had near-death experiences through sudden illness or accident and found that a substantial number (25 percent) had a new and powerful sense of death's omnipresence and nearness.
Yalom cites Noyes's clinical research to establish the near-death experience as a therapeutically significant boundary situation that permanently alters the experiencer's relationship to mortality.

I've been reading books about the near-death experience: Saved by the Light and Embraced by the Light. They really do a good job describing the DMT state. I'm reading them in such a familiar manner.
A research subject's testimony establishes experiential equivalence between documented near-death accounts and the DMT state, supporting Strassman's neurobiological hypothesis.

Her consciousness separated from her body, she moved rapidly through a tunnel, or tunnels, toward a warm, loving, all-knowing white light. Beings helped her on the way, and some even threatened to drag her down.
Strassman presents clinical session data in which a volunteer's DMT experience reproduces the canonical near-death phenomenology of bodily separation, tunnel passage, and encounter with luminous beings.

naturally occurring psychedelic states, such as contact with nonmaterial beings, and near-death and mystical experiences, resemble those induced by outside-administered DMT in our volunteers.
Strassman frames the research program's core hypothesis: that endogenous DMT mediates spontaneously occurring near-death and mystical states that parallel the effects of exogenously administered DMT.

near-death and mystical experiences, resemble those induced by outside-administered DMT in our volunteers. Many of the following series of studies build upon these similarities.
Strassman outlines a research agenda grounded in the structural similarity between near-death phenomenology and DMT-induced states, with the pineal gland as the proposed endogenous source.

I was refilled with a new hope and purpose in being alive… I experienced a feeling of unity with all things and a oneness with all people. After my psychic rebirth I also feel for everyone's pain. Everything was clear and bright.
Yalom documents the existential aftermath of confrontation with death — expressed through testimony from near-death survivors — as producing ego dissolution, unity experience, and radical reorientation to life.

A nekyia journey, like a near-death experience, involves decay—the dissolution of the self; a distillation—celestial feelings of ascent found in surrender, chaos, and death.
Keltner draws a structural parallel between the near-death experience and the archetypal nekyia journey, situating both within a cross-cultural pattern of self-dissolution and transcendent ascent.

Strassman illustrates the therapeutic potential latent within fear-inducing near-death-like DMT states, showing how confrontation with simulated dying can be transformatively reframed.

Andrea was terrified when the spirit molecule pulled her toward a near-death experience. However, she used her initial fear as a catalyst for some of the most immediately hair-raising DMT
The case of Andrea demonstrates that the near-death trajectory within a DMT session, though initially terrifying, can serve as a catalyst for psychological breakthrough rather than traumatic breakdown.

Nearing his own death at ninety-two, Pettersson observed: 'What will sustain me in my last moments is an infinite curiosity as to what is to follow.'
Keltner invokes Pettersson's death-facing stance as an instance of awe sustaining psychological equanimity at life's threshold, linking near-death orientation to wonder rather than terror.

the encounter with death on the perinatal level takes the form of a profound firsthand experience of the terminal agony that is rather complex and has emotional, philosophical, and spiritual as well as distinctly physiological facets.
Grof identifies the perinatal encounter with death as a multi-dimensional experiential matrix that shares phenomenological territory with clinical near-death accounts, grounding both in the psychedelic research paradigm.
