[NO Spoilers] How to dare...?

[brrrrainz]

a good thing would be to hide as soon as you hear a spine-chilling grunt. thats a quite reliable warning if the monster approaches, so lock yourself in a room and crouch behind furniture or a barrel (if you can't see it, it can't see you, right?). as in similar games like silent hill and dead space the music can also help you to decide what to do next. if it changes back into a slower, quiter tune, you are safe to venture forth.

and closing doors is a really good hint. this thing following you needs some time to break through doors, time you can use to find a good spot to hide.
