Doppelganger (dop·pel·gäng·er/ˈdäpəlˌɡaNGər/): an apparition or double of a living person.
Not to be mistaken with an identical twin, a doppelganger is an unexplained phenomena where you have a double of no direct relation. This double can be human, or apparition in nature, but is both unusual and creepy. Unlike Elena and Katherine from The Vampire Diaries, the tale of Emilie Sagee and her doppelganger may have some truth to it.
