Good thread - a lot of this is common for me also; fear of the dark, being home alone in general and jumping at noises, I do not shower after dark - never really thought about why. I also do not sleep on my back much - too scary. If I do not have a percise destination to go to, I don't go out -I don't know why, the tension is just too much. I'll even putting off going to the store or filling the gas tank unless I'm already out to or from work. And i can't do yoga next to guys (since a lot is on our back or exposed in some pose) and i can't do some of the mor exposing poses ever no matter who is there. But i can do them at home. I also, keep volumes down low so i can hear over them for any odd sound. I will watch movies, but no head phones when alone.
