You're probably familiar with the Ouija board, even if you were never been allowed to play with one as a kid. The idea of spirit writing goes back centuries, but it wasn't until Parker Brothers started manufacturing the Ouija Board in the '60s that this particular form of spirit communication became a slumber party hit. Ouija boards have been a pop culture mainstay for years — we wouldn't have Pazuzu had Regan not first communicated with Captain Howdy via Ouija in "The Exorcist." But what about real life? Is there any truth to Ouija possession? Maybe. These are the documented cases of people becoming possessed after using Ouija boards.
