Haven't found anything yet. Usually I get easily creeped by stuff like the zombies in OB and feral ghouls in FO, but Skyrim's equivalent, draugr, don't really have the same effect on me for some reason. I HATE spiders in real life, but in game they don't really creep me out, I was hoping they would
I remember vividly a moment I had while playing Oblivion. It was in some cave which was obscured by mist inside, and I saw the vague figure of a zombie shambling through the mist... that sent a shiver up me!
