Today after completing a quest i was near blind cliff cave and it was at night and i was on a bridge i heard a roar then saw a shadow of a dragon it scared the heck out of me but when i looked around i saw no dragon (until a few minutes later).

Probably a wolf that attacked me by surprise. I have jumped many times because of sudden sounds, but not because I found anything particulary scary.

Apocrypha is probably the closest thing to horror in Skyrim in my opinion, the lurkers look pretty creepy..

I have not been scared by this game, or any game really. I have been startled, surprised even, but not scared.

I think what gets the blood going the most for me are battles where I don't know if I am going to win, either because of the amount of enemies or my character's lack of preparation. That is the closest I get to being scared in a game.

Dunno what my bigest scare was but recently a Draugr scared me when I didn't know it was there; it seemed to blend into the surroundings and came out of nowhere.

I was in the market in Windhelm when the owner of Hollyfrost Farm was staring at me when I turned the camera. Scary as [censored]. He had that "naughty face".

Earlier on, about 20 hours of using Climates of Tamriel and got stuck in my first storm.
I pooped.

Going through Falmer-Infested Caves as a Stealth Character, can get really intense. Never know when a Falmer might be crouching around the corner.

The Molag Bal daedric quest in Markarth. I did not know what the [censored] was going on the first time I went into that divines-forsaken house.

The giant spider in Cronvangr Cave, because i thought i had killed them all and sprinted to the chest, and then the spider popped out in front of me....
