Nightmare

I don't know what it is, but I haven been getting at least one bad nightmare a month for about 6 months or so. I usually wake up thinking someone is in my apartment. Early this morning, I didn't feel that way as much as being scared. I felt anxiety kick in, like a heavy weight sitting on my chest. I was not even fully awake, but I had to slow my breathing and tell myself that it was only a dream.

I must have an intense fear that someone is going to break in. Maybe that book I read before going to bed didn't help, either...
