People can have visions when in danger, in hospital, or during attempted suicide {deathbed visions} {near-death experience}| (NDE). Near-death experiences can have tunnels or entry into darkness, out-of-body experiences, bright lights or emergence into light, peaceful and loving feelings, strange worlds, life-history memories, and choices to go back to the living world [Moody, 1975] [Morse, 1990] [Morse, 1993] [Parnia and Fenwick, 2002] [Parnia et al., 2001].
There can be peaceful feelings, out-of-body experiences, entries into darkness, visions of light, and emergences into light {Greyson NDE scale} [Ring, 1980].
Experiences can be regressions to childhood states. Mind feels love, peace, acceptance, and pureness, with focused attention, no criticism, and no available alternatives. Most near-death experiences are pleasant, but some are like hell [Parnia et al., 2001] [van Lommel et al., 2001].
stages
People first hear noises or move fast down tunnels or valleys. Then they feel that they are outside body but in same physical environment. Loneliness and timelessness feelings follow, with low emotions. People are invisible to others and cannot communicate. People feel no weight or other sense qualities. People feel peace, calm, joy, and love. People can know others' thoughts. Then friends or relatives that have died already come as spiritual helpers. Among them is a being of light, with personality. This being asks mental questions about readiness for death. Then people see a fast, accurate summary of their life from childhood to present. Then a barrier or border, a no-return line, approaches. However, people feel that they should go back and live, because it is not yet time, they have not yet done something, or people are calling them back. Then, preceded by unconsciousness, return to physical body is through head. Afterward, people feel that they must try to learn and love, with no fear of death or judgment and no worries about heaven or hell.
causes
Perhaps, unusual brain states cause near-death experiences {dying brain hypothesis}, as anoxia, stress, and fear activate brain [Blackmore, 1993].
Brain is often clinically dead or damaged {brain dead}, but experience can have happened before that [van Lommel et al., 2001].
No drugs cause near-death experiences [Parnia et al., 2001] [van Lommel et al., 2001].
comparisons
Near-death experiences are similar to high brain carbon-dioxide levels. Near-death experiences are similar to well-being feelings caused by brain endorphins. Near-death experiences are similar to autoscopic hallucinations. Near-death experiences are similar to LSD experiences. Near-death experiences are similar to sensory isolation experiences. Near-death experiences have no typical physiological symptoms [Parnia et al., 2001] [van Lommel et al., 2001].
