What about "Horror" in Amnesia?

[Kedjane]

Random dead body isn't scary.

Overture and the Tech Demo were certainly extremely scary for me but contained no corpses. How can that be?

Yeah? What about the guy falling out of nowhere in the Kennels? Saw some Youtube vid with a guy totally shitting in his pants at that place.

Also I believe corpses and blood can be used to increase tension and all, but a dead body completely still on the ground, well lit and without horror music, that won't be scary. All elements have to come together. Dead bodies shock and increase the feeling of vulnerability (typo?).
I thought the arms in the walls in the dreamworld-thing were pretty creepy.
