Good horror survival games?

just wanna know some horror survival games (in other words scary and usually one person trying to survive). already got both bioshocks and im considering dead space series, but personally im not a futuristic space man. please do not suggest any games off of movie franchises because, good god, i don't want silent hill or saw in which ill end up crapping my pants from sheer terror. im lookin for bioshock-equivalent terror. also please no kiddy horror games like dead rising, that was fun but not scary. sorry if i sound demanding, just havin a bad day and could go for some one on one dark room zombie killing
