Doppelganger?

Doppelgänger is the German word for a ghostly double of a living person. The word comes from doppel meaning "double" and gänger translated as "goer". The term has, in the vernacular, come to refer to any double of a person, most commonly in reference to a so-called evil twin, or to bilocation. Alternately, the word is used to describe a phenomenon where you catch your own image out of the corner of your eye. In some mythologies, seeing one's own doppelgänger is an omen of death. Queen Elizabeth I of England was shocked to see her doppelganger laid out on her bed. The queen died shortly thereafter.
