...the child half looked like me when I was youn....
I can only tell by what you say of this dream. It sounds like you. All of my dreams (I do not have any more night dreams of the abuse) were of me as a child. Some dreams were good dreams - which I needed.
I would ask myself these questions before I saw a therapist. A therapist who is good with dreams is who I would seek if you are NOT sure about this dream.
1. Is this dream traumatic?
2. Is the child happy - maybe you seeing yourself as being happy which can be very motivating.
3. Is this child hiding feelings? On the surface looks happy.
4. Is this dream something to be concerned about.
5. Do you recognize other things in the dream other than yourself?
