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. They usually cause problems and frighten living people. They exist either to avenge some injustice they experienced while alive, or because their soul is not ready to be released, as a consequence of their former way of life.
