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 exorcised.
Dybbuk is an abbreviation of דיבוק מרוח רעה dibbūq mē-rūaḥ rā‘ā ('a cleavage of an evil spirit'), or דיבוק מן החיצונים dibbūq min ha-ḥīṣōnīm ('dibbuk from the outside'), which is found in man. Dybbuk comes from the Hebrew word evil דִּיבּוּק dibbūq which means 'the act of sticking' and is a nominal form derived from the verb דָּבַק dāḇaq 'to adhere' or 'cling'.
The term first appears in a number of 16th-century writings, though it was ignored by mainstream scholarship until S. Ansky's play The Dybbuk popularised the concept in literary circles. Earlier accounts of possession (such as that given by Josephus) were of demonic possession rather than that of ghosts. These accounts advocated orthodoxy among the populace as a preventative measure. For example, it was suggested that a sloppily made mezuzah or entertaining doubt about Moses' crossing of the Red Sea opened one's household to dybbuk possession. Very precise details of names and locations have been included in accounts of dybbuk . Rabbi Yoel Teitelbaum, the Satmar rebbe (1887–1979), is reported to have supposedly advised an individual said to be possessed to consult a psychiatrist.
Traditionally, dybbuks tended to be male spirits who possessed women on the eve of their weddings typically in a sexual fashion by entering the women through their vaginas which is seen in Ansky's play. 
Ansky's play is a significant work of Yiddish theatre, and has been adapted a number of times by writers, composers, and other creators including Jerome Robbins/Leonard Bernstein and Tony Kushner. In the play, a young bride is possessed by the ghost of the man she was meant to marry, had her father not broken a marriage agreement.
There are other forms of soul transmigration in Jewish mythology. In contrast to the dybbuk, the ibbur (meaning "impregnation") is a positive possession, which happens when a righteous soul temporarily possesses a body. This is always done with consent, so that the soul can perform a mitzvah. The gilgul (Hebrew: גלגול הנשמות, literally 'rolling') puts forth the idea that a soul must live through many lives before it gains the wisdom to rejoin with God.
In popular culture
The dybbuk was featured as the main antagonist in the horror films The Unborn (2009), The Possession (2012), and Ezra (2017). Ezra, an Indian Malayalam-language film by Jay K, revolves around a dybbuk box, with references to Kabbalist traditions and occultism. It was remade in Hindi as Dybbuk (2021).

According to the review in the San Francisco Chronicle, Zimler's novel, "Deserves a place among the most important works of Holocaust literature."
