The dark doesn't bother me either, but that said I would think that if your trauma happened during the night, then you naturally would associate night time with bad things.

I agree with the gun thing. Not a good idea. When I lived at a different apartment, I went out one night with friends for dinner, when I unlocked the door to my apartment I froze. Someone had broke in through my bedroom window, gone through everything I owned, closets, drawers, cabinets. I called the cops. Yeah ok, hand print on the window, shoe prints of mud on my carpets. Sorry, but there is nothing we can do. I slept with a butcher knife under my bed for several months. I also installed better locks on my windows, and doors. I eventually and logically refused to let my anxiety get the best of me. I refused to be held a victim and let this incident rock my world.

I put the knife away, and went on with my life, but just a tad more cautious.
