Hallucinations

Medical studies have proven that when certain parts of the brain are stimulated, various perceptions are disturbed, such as visual, auditory, and tactile functions.  Various external stimuli such as very low frequency sound waves, high fields of electricity, chemicals or drugs can cause hallucinatory experiences that for the subject are indistinguishable from reality. Indeed, schizophrenics … Read more

Recordings of past events

Although most agree that these types of apparitions do appear to be "recorded" somehow in … Read more

The concept of a parallel universe is a fairly complex one.  To put it simply, this theory suggests that there are one or more (perhaps an infinite number) of complete universes co-existing with us on a plane we are generally … Read more

Magnetic fields

Magnetic waves consistently flow through our atmosphere and come from both natural and man-made sources. The fields then fluctuate due to a variety of factors such as heating by the sun, tidal forces from the sun and moon, the impact of photons from outer space and localized weather conditions, for example, lightning. Stevens says, "There … Read more

Infrasound

Infrasound is sound that is lower in frequency than 20 Hz (Hertz) or cycles per second, the normal limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher … Read more

Mental projections

Freud thought that ghosts are actually the visions of people who are afraid of death.  In this sense, ghosts would not be real at all but rather a projection of our subconcious mind.   Jung looked for answers in his theory of the collective unconscious,  the contents of which can in his view take on almost … Read more
