Recurrent dreams of dead bodies

This entire month of March, I’ve had 6 dreams about death, murder, or me stumbling upon a dead body someone left. Why am I finding these bodies? Idk. It’s graphic, vivid, the emotions I feel are real. It’s to the point where I dread sleeping because I know a nightmare is around the corner. I’ve spoken to my doctor and there isn’t much they can offer. Granted I probably sounded crazy when I went in. My dreams started with me stoning and innocent old man to death and then fleeing and getting away with it. Then they progressed to me witnessing a murder, and now I’m just finding bodies that have been dead for either a day or a couple hours. It’s like I stumble upon a crime scene. I got a psychological health assessment and they medically cleared me to go home. I wasn’t a threat to anyone. I do take Zoloft and have for 18 months now. Has this happened to anyone else? I wake up feeling disgusted and scared. It ruins my whole day.
