[SPOILER] What scare did you miss in the game?

I thought I would have seen this: http://www.youtube.com/watch?v=iwoUdlx6irI

And I wish there was at least one part where there was a monster WITHOUT the accompanying music. As it is now, I just hole up somewhere until the monster disappears. I know it's safe to come out when the music goes back to normal. Of course, this would require more work be put into the sound so I can hear every footstep echoing down the hall.
