The only type of horror stories I've written (with character) effectively are what I call "splatter stories," which gets its effect from gore or violence. What I've been dying to try out is a psychological horror story. Psychological horror, I've noticed, is far more common in films and video games, then in books or writings. I imagine it's because writing one is incredibly difficult or takes a lot of work and thought. (If you check this wikipedia article , examples include films and video games, but no books)

Even if I were to write one correctly, I would base the horror off of the main character's fears or ignorance, which may or may not be effective to the reader(s). If it's not effective, then I failed, and there's nothing I fear more then sucking at a story.

Does anyone have any experience with this type of writing? I'd love some suggestions...
