Sleep sounds good, I hope you rest well. I totally understand being spooked by a random unknown noise. I'm hyper-spookable if that makes sense. I'm very jumpy, and then I get paranoid about it. I once could just make out the shape of a tree in the dark, and it looked odd to me, not like a tree should, and I got so creeped out by it that I had to run really fast to my car (it was right by a friend's driveway) anytime I had to go near it, and try not to look at it until it was out of sight because it made me so uncomfortable. I even asked the friend to walk me to my car many times. Ah well.
