I dont know if its an trauma response or just one of those things

My dreams are really dark and messed up , very often its about some of my trauma or its something compeletly different such as very graphic suicide scenes or crime scenes or rape really by men or women , I wonder if its because I was exposed to some of that from being 5 , and its messed my head up ? I used to watch hard core porn when I was 8 so I think its really messed my head up. A lot of them is based on the abuse I had as an preteen , some is actually very realistic clips from when I got sexually assulted last year. Some are of amimals killing me or attacking me , I got bit by an dog in real life when I was about 10. Or dreams about me killing animals in self defense. No matter what I think about before I fall asleep , I cant stop having those dreams most nights. Some are even worst , such as my family murdering me or me comminting suicide. So many are from school when I got expelled which isnt scary just annoying. Should I ask my therapist ? I really want to get good dreams , Im genuinely freaked out by dreams like this and I want them to forever stop.
