'''Near-Death Experience''' (NDE) is the mainstream-research and cluster-engagement name for the phenomenology reported by individuals who have undergone life-threatening events (cardiac arrest, severe trauma, clinical-death conditions) and recovered, characterised by recurring features across reports: out-of-body experience, tunnel-passage, encounter with light, encounter with deceased or spiritual figures, life-review, and consciousness-mode shift.

== Research Field ==
* '''Raymond Moody 1975 ''Life After Life''.''' Originated "near-death experience" as research category; case-study compilation.
* '''Kenneth Ring 1980 ''Life at Death''.''' First systematic phenomenology study with experiencer-population sample.
* '''Bruce Greyson 1983 ''Journal of Nervous and Mental Disease''.''' Greyson NDE Scale developed; remains primary research-measurement instrument.
* '''International Association for Near-Death Studies (IANDS) 1981+.''' Professional society; ''Journal of Near-Death Studies'' peer-reviewed publication.
* '''Pim van Lommel 2001 ''Lancet'' study.''' Prospective cardiac-arrest study; 18% of survivors reported NDE phenomenology; landmark mainstream-medical-journal publication.
* '''Sam Parnia AWARE study 2008-2014.''' Multi-centre prospective study of cardiac-arrest NDE phenomenology including verified-perception checks.
* '''Bruce Greyson 2021 ''After''.''' Programme-summary by Greyson covering five decades of NDE research.

== Phenomenology Inventory ==
Recurring features across studies (Greyson Scale items + adjacent):

* '''Out-of-body experience.''' Reported locus of consciousness at distance from physical body.
* '''Tunnel-passage phenomenology.''' Reported passage through tunnel-like structure.
* '''Encounter with light.''' Reported encounter with intense, often described as loving, light.
* '''Encounter with deceased figures.''' Reported encounter with previously-deceased persons or spiritual figures.
* '''Life review.''' Reported rapid review of life events, sometimes from multiple perspectives.
* '''Border / point-of-no-return phenomenology.''' Reported encounter with apparent decision-point regarding return.
* '''Return decision.''' Reported volitional or instructed return to physical state.
* '''Sustained trait-level changes.''' Reported sustained post-NDE shifts: reduced death-fear, value-orientation shifts, increased compassion / equanimity.

== Documented Cases ==
* '''Verified-perception cases.''' Some NDE accounts include reports of events during clinically-unconscious periods; cases with subsequent verification published in NDE literature (e.g. Pam Reynolds case; Maria-shoe case at Harborview Medical Center).
* '''Cross-cultural data.''' NDE phenomenology reported across cultures with culture-specific symbolic content but consistent structural features.
* '''Blind-experiencer reports.''' Reported visual NDE phenomenology in congenitally blind individuals (Ring & Cooper 1999).
* '''Children's reports.''' NDE phenomenology reported in children (Atwater, Morse research).

== Mainstream-Explanatory Frameworks ==
Mainstream-skeptic explanatory accounts:

* '''Anoxic-brain hypothesis.''' Oxygen-deprivation produces hallucinatory phenomenology resembling NDE features.
* '''CO2-elevation hypothesis.''' Hypercapnia produces visual phenomenology resembling NDE features.
* '''Endorphin-release hypothesis.''' Endogenous-opioid release produces euphoric phenomenology.
* '''DMT-release hypothesis.''' Speculative endogenous-DMT release; some research support (Strassman).
* '''Temporal-lobe phenomenology hypothesis.''' Temporal-lobe seizure-class phenomenology accounts for some features.
* '''Expectancy-cultural-conditioning hypothesis.''' Cultural-narrative-conditioning shapes phenomenology.

Each account explains some features but not all reported phenomenology; current research treats NDE as not fully accounted for by single mainstream framework.

== Cluster Extensions ==
Cluster framing extends the documented base:

* '''Consciousness-persistence indicator.''' Cluster reading of verified-perception cases as evidence for [[Non-Local Consciousness|non-local consciousness]] persistence beyond classical-brain function.
* '''[[Astral]] coupling.''' Cluster framing of OBE-phenomenology as [[Astral Projection|astral-projection]]-mode access.
* '''[[Consciousness Levels]] glimpse.''' Cluster reading of light-encounter phenomenology as glimpse of higher-density consciousness modes.
* '''[[Wanderers]] differential phenomenology.''' Cluster claim of differential NDE phenomenology by operator class.
* '''[[Mass Collective Consciousness Event|Mass-coherence-event]] correlation.''' Cluster speculative reading.

* [[Non-Local Consciousness]] - existing umbrella
* [[Quantum Consciousness]] - existing substrate
* [[Anomalous Cognition]] - faculty umbrella
* [[Mass Collective Consciousness Event]] (J1) - mass-coherence event

* [[Integrated Information Theory]] (J4) - substrate physics
* [[Consciousness Levels]] (K3a) - developmental hub
* [[Awareness]] (K3a) - phenomenology baseline

== Quality-of-Engagement Discriminators ==
* '''Documented phenomenology.''' NDE phenomenology has substantial peer-reviewed research base.
* '''Multiple explanatory frameworks.''' No single mainstream framework accounts for all features; this is real, not cluster-claim.
* '''Cluster substrate-extension separable.''' Consciousness-persistence claim is SPECULATIVE extension beyond documented phenomenology base.
