ADHD, Depression, Get Dreams About A Fight Or Conflict, Have Ended Up Hitting My Partner. Reason For This Strange Behavior?

Hi, Every so often I dream about a fight or a conflict and I end up enraged and I have hit my gf while sleeping. I only started last year and it s happened three times. Last night I elbowed her in her head, as if I m acting out my dream. She was hurt and upset. We went bak to sleep and a little later on I woke up on top of her grabbing her. What the he ll is wrong with me? I suffer from depression and ADHD . Although I have suffered with depression for 3 years and I ve been diagnosed with ADHD for 12 years. Don t know if this is anything to do with it but it is worrying me. Because it is strange behaviour.
