Like many people I also experienced dread in the seas, and was perpetually convinced that all manner of terrors were waiting inches below me at all times. Imagine my disappointment when I discover there's nothing like that! Even Oblivion had that giant slaughterfish, which if you weren't expecting it (me) was pretty dang scary at the time.
If I had a bit more experience with Papyrus right now I'd mod one in myself. Someone else should do it in my stead.

Oh, one other thing... is there any mod or anything that allows Draugr to spawn randomly/wander around in the open world at night? As it is now, they're far too un-scary down in those crypts when you're constantly waiting for them to stand up so you can cut them down again. I think adding a pack of them occasionally to the night world would at least add some variety and an unexpected encounter. These types of things are coolest unexpected.
