How do I make the nightmares from my abusive relationship stop, and is it normal that they’re still happening???

I’ve been having vivid nightmares about my last relationship almost every night, or recurring dreams about her in general. I’m repeatedly pulled back to moments where she screamed at me, called me stupid, and ignored me for weeks until I begged just to be acknowledged. To earn her affection again, I had to endure punishment being bitten hard enough to bruise, being struck, and the time she threw a full water bottle at my face while I was driving, then screamed at me, calling me stupid and cursing at me. I’m in therapy, I’m taking care of myself, eating better, and genuinely trying to heal, but the nightmares won’t stop. I’m exhausted, desperate for relief, and I don’t know what else to do anymore. please I’m desperate for one good night of sleep I’m so tired.
