Help!

I am 25 weeks pregnant and I keep having horrible dreams of my husband cheating and dreams about me being raped.. I was raped over a year ago. I can't get these dreams to go away and it is breaking me down in so many ways. I'm scared to go to sleep. I'm fighting sleep. And every time my husband doesn't answer his phone for a while cause he is at work. These dreams start popping in my head. It is getting so bad I am getting sick from not being able to sleep. I'm already a high risk pregnancy and need to figure out how to control these dreams being I end up back in the hospital. Please tell me I'm not the only one having these kind of dreams while pregnant!
