Sleep paralysis can be defined in several ways. In terms of the experiencer, it can be described as "a visitation by a malevolent creature which attacked its victims as they slept" (Cox). More clinically, sleep paralysis is understood as "a transient,conscious state of involuntary immobility occurring when falling asleep or upon wakening" (Cheyne, 2002). Research into sleep paralysis has produced compelling evidence that the phenomenon can be explained by brain chemistry and physiology in conjunction with REM sleep. But is that all there is to it?
