A Dybbuk is a concept from Jewish folklore, referring to the spirit of a deceased person that possesses the body of a living individual. This spirit is believed to be trapped between the physical world and the afterlife, often due to unresolved issues or unfinished business. The Dybbuk seeks to communicate or fulfill its desires through the living host. In traditional Jewish belief, the Dybbuk can be exorcised through specific rituals, often performed by a Rabbi. The phenomenon has been popularized in literature and film, contributing to its portrayal as a haunting or malevolent presence in various cultural narratives.
