Hi, SuzyK, and welcome to Psych Central! I wouldn't be surprised if these dreams don't have something to do with what you have experienced.
Have you ever thought of leaving your husband? (Just wondering.)
I am so sorry about the loss of your child. You might find the Grief and Loss forum to be helpful. I hear that losing a child is one of the hardest things for a parent to go through, and even a miscarriage takes its toll.
