I want to become more brave

[Culinus]

Is it normal that the screen zooms in and out slightly all the time and that the screen often leans towards a side and isnt straight? I thought things like that were supposed to happen when u go insane not when I have "Crystal clear" as status.

Also I can hear my characters breath which is unpleasant.

Things like that usually happens after some form of an event has taken place, and really has nothing to do with your sanity level. When you start to loose sanity you'll start to hear things (or rather, more things like insects / footsteps / chains) and your vision will become blurred / distorted.

As for becoming more brave; I don't think there are a lot of tips that will help you without ruining the game experience. The game is supposed to be scary. Best thing is to push yourself through it without standing around to "consider" whether or not you should enter that room / walk down that hallway.
