The Entity: Sleep Paralysis examines the phenomenon of sleep paralysis, the state in which a person cannot move as they pass from sleep to a woken state.
The hallucinations from sleep paralysis most likely contributed to the vivid myths, tales, legends and stories that have been perpetuated throughout the years and shared amongst the cultures around the world.
During a sleep paralysis episode, one may hallucinate (hear, feel, or see things that are not there), which often results in fear. These episodes generally last less than a couple of minutes but can feel like an eternity to the victim.
Today scientists believe sleep paralysis can occur in those who are otherwise healthy or those with narcolepsy, or it may run in families as a result of specific genetic changes.
The condition can be triggered by sleep deprivation, psychological stress, or abnormal sleep cycles. The underlying mechanism is believed to involve a dysfunction in REM sleep.
Although the documentary documents the psychological and scientific studies, it also doesn’t shy away from the condition being paranormal.
In the end, The Entity: Sleep Paralysis leaves it up to the viewer to decide whether or not it’s all in the brain or paranormal activity.
