Doppelgänger

A doppelgänger (; German: [ˈdɔpl̩ˌɡɛŋɐ] (listen), literally "double-walker") or doppelganger is a biologically unrelated look-alike, or a double, of a living person. In fiction and mythology, a doppelgänger is often portrayed as a ghostly or paranormal phenomenon and usually seen as a harbinger of bad luck. Other traditions and stories equate a doppelgänger with an evil twin. In modern times, the term twin stranger is occasionally used. The word "doppelgänger" is often used in a more general and neutral sense, and in slang, to describe any person who physically resembles another person. more »
