I always wear my gun while I'm awake, no matter what I'm doing. When I hear a noise from bed I get up and take my pistol to check. 99% of the time, it was just some noise and I don't actually expect to find a person anywhere. If I heard the door, breaking glass, interior voices, or anything else that makes me suspect that someone is actually on premises, then I'll pull the loaded (not chambered) shotgun out of the closet. That may change a little when I actually own my house though. Right now in the apartment people walk around right outside my windows all the time. In a house, they'll have no reason to be in my yard which will change the situation a bit.
