The whole area gets flooded and there is an invisible water monster chasing you. If you listen closely, it sounds like a Brute is providing some of the vocals. Also, the piano in the main hall can be heard playing when you are in another room - but it stops when you get close to it.
You are never in danger of dying here, but you may be afraid that you are. Ambient noise is put to good effect and the deep bellow of a monster can be heard at times as if it is around the corner, and in truth, there is nobody there. The zone simply named 'Archives' can be deeply unsettling the first time.Overall the soundtrack can give out a heightened sense of paranoia. Some tracks involve haunting choirs while others feature ominous moaning. The ambient music for the game does a great job of creating an unsettling and foreboding atmosphere.
