The Dybbuk Box

What's a Dybbuk Box? Exactly. According to Jewish mythology, a Dybbuk is a malevolent spirit -- basically the closest thing the Jews have to a devil. A man's encounter with a Dybbuk box--made to hold wine--was transformed into a book, which was then used as the foundation for the movie "The Possession." Supposedly the Dybbuk doesn't even like being mentioned or talked about, so I should shut up now.
