The Witches
Some horror movies are specifically designed to scare kids, and this is one of them. Witches around the globe change their faces to appear as normal-looking, professional women. However, they use these disguises to trap children in places where they can conduct rituals. Using witch magic, they turn the kids into mice and stomp on them!
The Exorcist
The Exorcist was one of the first true horror movies that had ever been made. The craziest thing about this movie is that it is actually based on a true story, although it was dramatized a little bit for the sake of the plot. The Exorcist is about the last official catholic exorcism that had been conducted on a young man who was referred to as "Roland Doe" because nobody knew who he was.
