Are you one of those horror junkies who spend their free time watching horror movies and listening to true crime podcasts until late at night? Welcome to the club, our twisted friend!

We’ve all seen some crazy stuff. From creepy-crawly insects to serial killers and haunted houses, there’s nothing we won’t watch if it’s on the screen in front of us. But as frightening as these movies and shows are, some scary facts about our world make reality way more disturbing than fiction could ever be. For example, did you know that Aztec priests offered still-beating hearts to the gods, freshly severed from sacrificial victims? Or that safety coffins were invented because so many people got accidentally buried alive? Or again, that there’s a museum in Pennsylvania that displays mutations, tumors, and anomalies for everyone to see?

Well, you already know the world is full of creepy things, but it’s better to remind ourselves of how much from time to time, right? So here we are with tons of other disturbing facts for you to enjoy! You might be surprised by how many of them sound like urban legends but are actually true.
