What in Skyrim really gives you a creeeepy feeling? For me, I'm not impressed by dragons, ghosts, draugr or whatever monster. However, there's something that really gives me a chill. Sometimes when you approach a corpse, it opens or closes its eyes, snaps shut its mouth, jerks a limb or some other reaction. I wonder if it's intentional by the designers (in the real world recently deceased cadavers sometimes have reflexes). But it always gives me a little jolt.
