Dybbuks are said to have escaped from Gehenna (a Hebrew term loosely analogous to the concept of hell)
The Dybbuk is a demon from Jewish and traditions. The spirit possesses humans and uses their body to exercise its will. In Hebrew, “dybbuk” means “clinging” or “cleaving,” and that is from where the malevolent possessing spirit derives its name. It is generally believed that the spirit is the disembodied soul of a deceased person. According to tradition, a Dybbuk will possess a human when that soul is left unfilled with its original accomplishments here on Earth. The spirit will often target humans that are restless, people who lack a continuity between their soul and body. It will then possess and take control of the body in an effort to carry out its tasks.
