Are demons real? Though evil spirits possessing the body of a hapless human victim seems like the stuff of science fiction, the possibility of being possessed by demons is, in fact, a common belief held by religions around the world.

Most religions offer prayers, spells, or incantations that are used to remove these invading spirits via exorcism rituals.

As hard as it may be to believe, countless accounts by victims and witnesses dating back to ancient times are hard to ignore. Let's explore ten cases of truly scary and, by all accounts, real demonic possession.
