Nightmare days#2 , how do I make it stop ✋

I just woke from again from a nightmare, I wanted to scream in shock but I tried to calm myself . In the dream I can see myself standing by door and it unlocks , he has the key and comes in. I can see he isn’t aggressive but somehow he becomes aggressive and I run to my door and he runs after me , I’m somehow on the floor screaming and a neighbor comes out and stabs him . I’m inside my apartment and the neighbor comes in reassuring everything is okay but somehow I see my exs body on the floor in my apt and I don’t pay attention to it and he gets up and runs towards me pushes aside the neighbor where they fall and don’t wake up now I run in the back and I grab my son somehow I manage to get out but he grabs my mom who comes out of nowhere which I’m lost about and he’s choking her out while I run out to get the police , we come in I can see him still choking her and I tell I never felt anger in my life from this dream in the dream , my mom face is between his legs and we won’t give up somehow I get in front of the officer and he gets shot , I woke with horror in my face and this was so vivid I just feel anger and a headache . It makes me wonder if my deceased mother ever really saw me getting beat on and I know she would trade spots with me , my mom was protective and I feel trauma all over again.. how the hell is this healing but I’m being traumatized in my dreams
