Horror movies are scary enough, but if you find out that they are based on true stories they can be downright terrifying! These 15 movies were all (loosely) based on true events. So hold on tight and read on, if you dare!
A Nightmare on Elm Street was a movie where you weren't even safe inside your dreams. Freddy Kueger would hunt you down while you slept and kill you in your nightmares. It is surprisingly based on a real-life series of deaths that were reported in the LA Times about Southeast Asian immigrant men who were dying in their sleep from unknown causes. One of them even reported having strange nightmares before he died, and was heard screaming and thrashing around in his sleep.
