I'm similar... A book never seems to scare me so much - I don't jump or look away or anything like that which I do for a movie. However, I do have the tendency to simply close my book (Pet Sematary rings a bell) and just think ask myself 'what the hell? What have I just read?' So yeah, books tend to make me more uncomfortable just because you get a more descriptive view of it, not just what you see on a screen. Being a huge horror fan, I don't tend to get scared too often anyways, just creeped out by the unknown...I've said before, books don't scare me, so if I had to pick one I'd say mordred gave me the creeps, especially in spider form.
