附鬼（Dybbuk）是犹太传说中的一种会附身的鬼魂。据传说，如果死者生前有罪，那死后便会成为游魂，还能进入生者的体内，并控制其行为。

In Jewish mythology, a dybbuk (Yiddish:דיבוק‎, from the Hebrew verb דָּבַק dāḇaq meaning "adhere" or "cling") is a malicious possessing spirit believed to be the dislocated soul of a dead person. It supposedly leaves the host body once it has accomplished its goal, sometimes after being helped.
