Since when is One Tree Hill Scary??

I don't know if you watch OTH, but it's your typical high school teeny bopper show about kids pretending to be older than they really are yaddayaddayadda...Soo I download it on occasion (along with House and Grey's Anatomy), just to watch when i'm bored or before going to bed. Tonight I watched OTH season 4 episode 5 and it was really really scary. Like full out, run up the stairs horror movie scream, dude attacking pretty girl with a faser scary. However I do tend to get scared watching movies like "Club Dread" ...Anyways, the point of this is that I watch these silly TV shows before I go to bed to unwind from studying and checking PBs, tympanic temps, pulse-ox and so on at the hospital all day, because usually they have little story plot and are quite entertaining when i'm half asleep. this episode was very disappointing b/c now i'm scared to sleep by myself in case a strange long lost brother I never knew I had decides to come find me and go psycho on my ass and try to kill me.
