In Jewish mythology, a dybbuk (/ˈdɪbək/; 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.[1] It supposedly leaves the host body once it has accomplished its goal, sometimes after being exorcised.[2][3][4]
