Dybbuk, in the folklore of Hassidic Jews in Eastern Europe, is a spirit of a dead man who takes possession of the body of the person to whom he was attached in his lifetime. Michal Waszynski's "The Dybbuk", shot in Poland in 1937, set on stage this figure, based on the play by Sholem An-Ski, a Russian ethnographer, and on the expressionist aesthetics. Waszynski's film is a fiction witness that contains traces of the existence of Yiddish culture and the magical beliefs of Eastern European Jews before the Second World War, from which the legend of Dybbuk is originated. Our article questions the images of magic and mysticism present in Waszynski's film in order to apprehend the self-representation of a disappeared world.
