The annals of Wikipedia are full of some seriously creepy stuff. As the makeshift source for all human knowledge, Wikipedia has plenty of tales of the weird, macabre, and unexplained. If Wikipedia were a house, this would be the creepy attic that everyone thinks is haunted. Excluding the unverified, poorly sourced, and completely made up, these are the creepiest pages that Wikipedia has to offer.
Perhaps what makes all these stories so scary is that the events really occurred. Here, we are visiting some seriously dark corners of the human psyche. Some of the events will shock you. Some even cross over into the supernatural realm, or at least raise the question, could the supernatural be real? You can judge for yourself, thanks to the great sourcing structure of Wikipedia.
Reading on, you might encounter some facts that you wish you hadn't learned. You've been warned.
