I don't consider the whole "Ghost jumps out of closet and yells BOO" scary. Thats closer to being startled.
As for true horror? Well nothing is scarier than nothing. No matter how scary the monster really is, it pales in comparison to waiting to see it.
After that, being watched, being followed, and being stalked are the scariest things. Especialy if you don't know where your being watched from.
True horror is all about atmosphere and tension.
EDIT: Scariest video series I've ever seen was Marble Hornets. Best atmosphere goes to the Blair Witch Project. As for games, well the pitch-black segments of Half Life 2 Episode 1 gets a honerable mention.
