See, that's why I watch scary movies. I love that what-was-that-bump-in-the-night-I-can't-sleep feeling once in a while. What movie did you watch?
Well, the last time this happened I think it was because of a comic book I read (walking dead?). See I don't actually get scared when I'm reading or watching the content. But my mind does weird stuff to me once I fall asleep. It probably has to do with general stress more than anything. :/
I actually get kind of annoyed when I watch a "scary" movie that's good and creepy and then, right at the end, it gets so ridiculous that it totally ruins my freaked-out mood. Off the top of my head, "The Ring," both "Paranormal Activity" movies, and "The Last Exorcism" were all like that; I wanna be scared, dammit! "The Fourth Kind" was the last movie I tossed and turned over a little bit, until my brother-in-law tried to convince me it was real; after that, I just felt silly.
