Shortly after starting work in EMS with a company that works 24 hour shifts, I've been having issues with sleeping (waking, actually) that I've since learned is called sleep paralysis.
Upon some research, I've also learned that one of the possible causes of sleep paralysis invovles disruption of one's sleep schedule or circadian rhythm. This got me to thinking, how many of my fellow EMS workers have had episodes of sleep paralysis?

Physiologically, sleep paralysis is closely related to REM atonia, the paralysis that occurs as a natural part of REM (rapid eye movement) sleep. Sleep paralysis occurs either when falling asleep, or when awakening. When it occurs upon falling asleep, the person remains aware while the body shuts down for REM sleep, and it is called hypnagogic or predormital sleep paralysis. When it occurs upon awakening, the person becomes aware before the REM cycle is complete, and it is called hypnopompic or postdormital. The paralysis can last from several seconds to several minutes "by which the individual may experience panic symptoms". (described below) As the correlation with REM sleep suggests, the paralysis is not entirely complete; use of EOG traces shows that eye movement is still possible during such episodes. When there is an absence of narcolepsy, sleep paralysis is referred to as isolated sleep paralysis (ISP).
In addition, the paralysis may be accompanied by terrifying hallucinations (hypnopompic or hypnagogic) and an acute sense of danger. Sleep paralysis is particularly frightening to the individual because of the vividness of such hallucinations.[8] The hallucinatory element to sleep paralysis makes it even more likely that someone will interpret the experience as a dream, since completely fanciful or dream-like objects may appear in the room alongside one's normal vision.
