Doppelgänger !

So , this is about doppelgänger .

     A doppelganger, can be the ghost of a living person or any other sort of physical double that look very similar to the ghosts of the deceased. The word doppelganger comes from the German Doppelgaenger, literally meaning “double-goer.”
In some cases a person will come upon his own doppelganger who is typically engaged in some future activity. Scientists at the University Hospital in Geneva, Switzerland discovered that electrical stimulation of the brain, used to treat epilepsy, can produce the sensation of a doppelganger’s presence in the patient.

In folklore, the doppelganger is said to have no shadow or reflection, much like vampires in some traditions. Seeing one’s own doppelganger or the doppelganger of a friend or relative is considered very bad luck, often indicating death or serious illness.

Doppelgangers appear often in various types of fiction. Guy de Maupassant’s short story Lui (Him) tells of the writer’s own experience with a doppelganger. In Edgar Allan Poe’s short story “William Wilson”, the protagonist of questionable morality is dogged by his doppelganger when his morals fail. In Charles Williams’ novel, Descent into Hell, a doppelganger is a significant part of the plot as the heroine’s fear of the doppelganger drives relationships and choices. In Stephen King’s book The Dark Half, the main character, Thad Beaumont, thinks he’s being tormented by a murderous doppelganger. But is revealed later that he’s indeed the ghost of Thad’s twin who had died in his childhood, and acquired an own life when Thad invented a fictional character for the book he was writing.
