Over the past decade increasing evidence has emerged indicating that insomnia, especially when it occurs in a setting of short sleep, is related to heart disease.
Alien abduction experiences may be due to a wide range of causes including hypnotic phenomena, surgical anesthesia, sleep state dissociations, and maybe alien abductions.
Alien abduction experiences are probably more common than we realize. They are often frightening, sometimes life transforming, and can have both positive and negative aftereffects.
Experiencing "alien abduction" can change a life—for good or ill. Is it similar to other anomalous experiences or is it something else entirely?
