Scary movies might seem like all fun and games — unless you're watching one that's non-fiction, and then you suddenly become convinced that the creaks you hear at night are not actually coming from old pipes. Documentaries, especially frightening ones, can really influence the way you think about any given subject, and leave you wondering long and hard about the state of the world. I gathered a list of docs that are chilling and seem just way too crazy to possibly be real, but somehow are. When you know exactly what humans are capable of by watching these movies, it's slightly terrifying. These documentaries are bound to give you nightmares, with subject matters like cannibalism, rape, animal cruelty, murder, and mental illness.
I'm speaking for myself when I say you probably don't want to marathon these movies, as you're sure to find something or many things on this list that will haunt you for years to come. With that said, though, if you're gutsy enough to sit through all of these films without flinching, I may need to update the list with your story. But seriously, I hope you can get some sleep after checking out some of these eerie true stories.
