Reoccurring nightmares

tldr: im killing people in my nightmares in very horrific ways and i have zero clue why i am having these nightmares

Okay, for the past week or so ive been having reoccurring nightmares of murdering people in very horrific ways (slicing their necks open, shooting them, gutting them, choking them, mass murder, etc) sometimes i will have a helper that will also kill me at the end of the nightmare which wakes me up panicking because it felt real. this morning was the worst one ive had where i was in the country and i killed a family of 5, my helper took the knife and sliced my face and neck open and gutted me. like i said i have no clue why im having these nightmares. im not stressed with anything, ive been feeling okay emotionally and physically, and im in a good spot in life. has anyone else had these types of nightmares?? im freaking out now 😭
