Hi and Welcome.
I sense a lot of pent-up anger in you. But the fact that you are getting your frustrations out in the dream is a good sign--better than kicking someone's butt for real.
Are you angry at the father of your child in reality? Does he possess the maturity for fatherhood? Judging from your dreams, my guess is no. Does he fool around a lot with other women? You may have to be both mommy and daddy in that case.
If the anger is not toward him in reality, than perhaps it's geared toward someone else who has some control over your life or your baby's?
