No matter how terrifying a horror movie can be, you know in the back of your head that the events that are taking place aren't real. There's no way a a kid's doll became possessed by the soul of a serial killer and went on a rampage, murdering everyone in sight. Don't get too comfy because plenty of these movies have roots in reality.
Now, before you go burning all your precious Cabbage Patch Kids, you'll probably want to know which horror classics are based on actual or true events. Luckily, lots of horror movies seem to pull from one serial killer, and he's been dead since the '80s, so there's no need to cower in the corner until the end of days. Some of these films stray far from the bounds of reality, while others stick true to their non-fiction source material. Either way, they're all terrifying in their own rights.
