It is a proven fact that when one is sleep deprived, hallucinations occur as a result. Truck drivers, airplane pilots, or anyone who must fight sleep sometimes experience visual apparitions of flashing, streaking, or steady white lights, ghostly or distorted faces, animals, and an increased tendency to focus on one object causing the surroundings to appear dark, creating a tunnel-like effect. When asleep, tired, or in darkness, the eyes are more prone to make misidentifications of normal objects which would easily have been recognized in proper conditions. The mind can also cause an inanimate object appear to have movement. Our tendency to personify inanimate objects is another factor which may cause or affect misidentifications and hallucinations.
People often attribute human characteristics and features to similar looking objects.
A heap of clothing or a hanging coat in a dark room, to tired eyes, can take on a life-like supernatural form. These factors, along with the uncertainty that what happened actually happened, could lead a person to confirm the reality of the event under hypnosis. The Tectonic Theory and UFOs Strange arial lights have been found to be caused by the movements of rocks along fault lines. The Tectonic Strain Theory states that the light is caused by peizo-electricity. Another related seismic event is the release of lithomagnetic rays.
