That might be true, but I still think the monster from Amnesia are probably killable if the character had some sense and tried a tactic other than running, hiding, and wetting himself. Perhaps a close-up approach isn't the best idea, but how about tossing semi-heavy or sharp objects at its face until it stops moving? As far as I'm aware, the majority of the monsters aren't particularly smart or fast. I could be mistaken of course, as I have personally not played Amnesia.
As for the rest, you are right in a way, but it doesn't exactly scare me then. I ran into a deathclaw when I was pretty weak still at some point. It didn't really scare me, but rather it annoyed me a bit. In most cases, my intial thought is "What is this, and how do I kill it?" As soon as I figure out I can't yet, I figure it's best left alone for now, and try to come back another time, when I'm a bit stronger.
Like I said, I can't think of anything that actually scares me in a game. Simply because, there isn't anything that really scares me, sound or otherwise.
