For me, horror movies tend to come in two different types, the ones that scare you for the duration of the film but leave you alone afterwards (with such films as Scream, Halloween, Grave Encounters and Leprechaun) and the ones that scare you during the film and for the rest of your life (with the films below to name a few). The main difference that I can see between the two is that the second set is more insidious with its scares. Sure, these films below have their jump scares and scary soundtracks and creepy looking antagonists, but they also have a feature that will remind you of them when you are in the dark on your own. And so below are 3 films that scare the crap out of you but not for the reasons you think. OBVIOUSLY THIS LIST HAS SPOILERS PEOPLE, SO CONSIDER YOURSELF WARNED!
