"People have been experiencing sleep paralysis and nightmares since the beginning of time.
In the middle ages, many people claimed to have been attacked
by succubus and incubus type beings. In modern times, some people believe that alien abductions are part of sleep
paralysis experiences. Despite the fact that there has been scientific research done on the phenomenon, and that there
is a logical explanation for much of it, some are still so moved (and frightened) by their experiences that they can't help but feel that there really was
something supernatural involved."
