I've had plenty of Intense moments,but the most recent one had to be when I broke into a shopkeepers house and when I turned around she was straight in my face.It always makes me jump when shopkeepers are suddenly behind me and scream without warning.Also when I first started Skyrim I had a very Immense fear of Trolls. What are your most Intense moments on the Lands of Skyrim.

i was just starting a new character Level 2 and i hear something strange and i turn around just in time to see two sabre cats pouncing at me needless to say it did not end well

When I started the DG Aetherium quest, walking into that dark dwemer hallway and hears a ghostly voice; honestly freaked me out a little.
Also that lighthouse with the journals about scratching sounds through the walls, and actually finding out what they are. Some good Lovecraft settings there.

I'd say that a giant spider suddenly dropping down from the ceiling when I enter a chamber ranks right up there for me.

I also became extremely creeped out by the steam-hiss you hear all the time in Dwemer ruins, my first time through one I didn't realize that's what it was and thought it was some creepy sound the Falmer made when they were skulking around in the shadows. Now even though I know better, I can't break the association in my mind so every time I hear that noise I half-expect a Falmer to pop up from somewhere. After all this time it still makes visits to Understone Keep slightly nerve-wracking.

Going into some random cave, completing an objective, then realizing there is more area to explore inside, continuing on down to see what's there, then suddenly seeing tell-tale signs of Dwemer influence and Falmer infestation and coming around a corner and realizing that I've just stumbled on a much larger bunch of Falmer than I was prepared to deal with. I had this happen while rescuing some dude on (I think) a Companions quest, I found him and let him out and thought "well while I'm here I might as well clear the place" and kept going thinking we would soon finish the dungeon and come to an exit that looped us back around to the entrance again. Uh... not so much. At first it was just one or two Falmer and then suddenly they were coming in droves. I barely got the poor guy out of there alive.

First time I was up against vampires. They were my most dreaded enemy in Morrowind, and the association was still there. (I've grown used to them now, though - my most dreaded Skyrim enemy is probably the Chaurus Reaper. Hearing that clicking noise that sounds like giant cockroach... Brrr.)
