In Jewish folklore, a dybbuk is a malicious possessing spirit, believed to be the dislocated soul of a dead person.
Dybbuks are said to have escaped from Gehenna or to have been turned away from Gehenna for serious transgressions, such as suicide, for which the soul is denied entry. The word "dybbuk" is derived from the Hebrew דיבוק, meaning "attachment." The dybbuk attaches itself to the body of a living person and inhabits the flesh. According to belief, a soul that has been unable to fulfill its function during its lifetime is given another opportunity to do so in dybbuk form. It supposedly leaves the host body once it has accomplished its goal, sometimes after being helped.
"An evil spirit of Jewish lore. They are said to possess people. Unable to gain a new body, it searches for humans to attach to. Once driven away, the lost soul may return to the earth with a new body, or may be cast into Hell."
