Does anyone have nightmares?

I have nightmares about what happened to me. I wake up crying and my hubbie doesn't know what to do to make me feel better. I can't bring myself to tell him exact details about what happened, it's just too hard to talk about. Sometimes certain things remind me about it and I get upset. I try to function normally and forget what happened, but it's kinda like when you hear a song that reminds you of something--it just happens randomly. Does this happen to anyone else?
