If you get a chance check out a movie called "The Decent" it was well done and has a very erie feel to it. If you are claustrophobic and scared of the dark as well as things coming to kill you that you can't see and you don't know where you are! This is the movie for you.. I would reccomend it to everyone.
i dont really watch scary movies, but i did see a part of the exorcist that freaked me out really bad
