Me as well, I'll be pretty hesitant about going into dungeons for a while...
I was actually playing Oblivion the other day.. I just got my first 10 hours logged in the game. I went down into a dungeon and heard a noise that stopped me in my tracks where I contemplated turning around and leaving the dungeon.
I later found out it was just some skeleton warrior type monsters, (because I fell through a rusty gate to the bottom floor of the dungeon where I found myself terrified and drawing my sword) but the sound was exactly the same sound that the Giant Dread Spiders from Ultima Online: Mondain's Legacy(1997) make.
I am convinced they like.. licensed the same sounds for these two monsters. It sent a shriek up my spine.
