Do you have an exact double somewhere in the world? Can a person be in two places at once? There are many intriguing accounts throughout history of people who claim to have either encountered apparitions of themselves - their doppelgangers - or have experienced the phenomenon of bilocation, being in two separate locations at the very same time.
"Doppelganger" is German for "double walker" - a shadow self that is thought to accompany every person. Traditionally, it is said that only the owner of the doppelganger can see this phantom self, and that it can be a harbinger of death. Occasionally, however, a doppelganger can be seen by a person's friends or family, resulting in quite a bit of confusion.
In instances of bilocation, a person can either spontaneously or willingly project his or her double, known as a "wraith," to a remote location. This double is indistinguishable from the real person and can interact with others just as the real person would.
