According to a new study, many persons with a Near Death Experience (NDE) have symptoms of REM sleep intruding into wakefulness:
For 60 percent of those who had been through an NDE, the rapid-eye movement (REM) state of sleep intrudes into their regular consciousness while awake, the study found. Both before and after their traumatic event, these people had experiences that include waking up and not being able to move, sudden muscle weakness in their legs, and hearing sounds that no one else hears upon waking or falling asleep.
Persons with narcolepsy commonly have symptoms of REM sleep intruding into wakefulness, including sleep paralysis (waking up and not being able to move), cataplexy (sudden bilateral muscle weakness/limpness in response to strong emotion) and hypnagogic/hypnopompic hallucinations (hallucinations, usually visual, as one is falling asleep or waking up).
These symptoms occur when features of REM sleep (muscle paralysis, dreams) occur during wakefulness.
I wonder Near Death Experiences are more common in narcoleptics??
