Wiedergänger
In German, the term Wiedergänger (German pronunciation: [ˈviːdɐˌɡɛŋɐ] ) is a term for a revenant and different ghost phenomena from different cultural areas, meaning "re-walker", or by extension, "one who walks again"; cognate to Scandinavian gjenganger ("again-walker"). The core of the wiedergänger myth is the concept of the deceased, who—often in the form of a physical phenomenon—return to the world of the living.
