Currently, when you sit (v) or sleep (b) for resting, you can rotate your character in a 360 degree rotation and look all around you. This isn't very practical, as normally when you sit, you have about 180 degree, maybe a little less, field of view. Having the 360 allows you to constantly be looking around you, and a "sneak" won't be able to creep up on someone sitting or sleeping, when they are supposed to be at their most vulnerable.

I would suggest not allowing camera rotation at all when sitting, and a "dimmed" view when sleeping i.e. the screen goes much darker, maybe not fully black, but definitely darker, when sleeping.
