Wiedergänger
The name Wiedergänger refers to different zombie or ghost phenomena from different cultural areas. The word means "one who walks again" in German. 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. German beliefs. In different parts of Germany, until the early  20th century, the belief was common that dead ones lived on, after their death, and exerted a disastrous influence from the grave. This influence was believed to be partly done via a telepathic effect (sympathy charm), so that the "nachzehrer", as the villain was called, did not need to rise from the grave and still could suck the vitality from living persons with his open mouth, his open eye and by gnawing on the burial shroud. Other undead, in the belief of the people, rose from the graves and jumped on the back of night ramblers. This "Aufhocker" could assume  different shapes, for example in the Rhineland, the form of the werewolf. The humans had to carry him, frequently as far as to the wall of the churchyard or to the place where the body was buried. The aufhocker (also called "huckop" or "huckupp") became ever more heavy, and the victim would finally break down exhausted or dead. In some legends, the troubled humans succeeded in banishing or redeeming the villain by a spell or a prayer. Especially in the areas marked by Catholicism the belief of the up-squatting wiedergänger merged with the belief of the soul, so that  folklorists around 1920 had considerable difficulties to separate a belief in ghosts from the old nuclear belief of the undead wiedergänger. The Aufhocker after all could, according to the tradition, not be a ghost, because he had a tangible body, which also increased in weight from step to step, which would not have been possible for an immaterial spirit. Another form of the physical wiedergänger is the headless rider that, frequently mentioned in West German legends, entered into world literature and even into the history of film through the American poet Washington Irving and his novel "The Legend of Sleepy  Hollow". Nordic mythology. In the sagas, wiedergänger in the form of draugar are a frequent motif. This occurs, for example, in the Hrómundar saga Gripssonar or in the Laxdœla saga. Whoever met a wiedergänger is often threatened by imminent death. Remarkable here is the stress on the physicality of the wiedergänger, which on the one hand shows in its superhuman power, but on the other hand, in its vulnerability: draugar can be killed by decapitation.
