I like reading up on creepypastas but I'm the biggest wuss to reading them. Day/Night I'm scared of the paranormal. Things like Ghost Adventures, Lost Tapes, and Creepypasta have indeed messed up my sleep schedule. Not too badly though, I just sleep with my back against a wall and extra sensitive to sound.
Recently I started watching Marble Hornets and it scares me to death but I keep watching it for some reason. Usually I hold onto something (ex: extra pillow) while sleeping with a back against a wall (if bed is flush to wall). The feeling of being surrounded by things I understand comforts me quite a bit actually. At least for me, I don't like having my back side exposed and it bothers me when I don't feel a constant pressure back there so that's my treatment for nightly terrors.
