I know this isnt an unheard of dream but I semi frequently maybe once a year sometimes a few times sometimes just once I will have a dream where its a real memory I had, somewhere I really was once etc. but in the dream ive killed someone. It rarely happens in the dream, the dream is always the aftermath. Like last night I was coming back from a camping trip with friends and a bunch of our bags spilled on the side of the road, some ranger was like halt! Theres been a murder I need to inspect your bags. In that moment in the dream il remember that I killed someone and start thinking "but I cleaned the bag right surely I cleaned the bag I transported his chopped up body parts in". The ranger looks in my bag and there is some bloodstains and a blood soaked facemask but I either came up with a reason or it wasnt enough blood to make sense and hes suspicious but moves on. Fairly standard, the feeling is always guilt and fear of being caught, and that is something I used to struggle with a lot. And in fact im not positive but these dreams I think do happen around when maybe im doing something I shouldnt. Maybe im secretly using some drug, maybe I had an interaction with somebody I wished I didnt and feel guilty about talking to them about so much, maybe I havent told my mom about some change in my life she would want to know about.
But all my dreams are like that, they always evoke some contemporary feeling for me and its pretty straightforward what its about and sometimes even what I have to do. I might have a dream about a great longing and sadness and joy about reconnecting with someone I lost touch with and its clear my brains trying to tell me its making me sad even if I try to push that feeling down. So maybe same here I feel a guilt about something that I really shouldnt feel guilty about, but I do anyways, and my dream wants to evoke that.
However one, why murder and two only with this specific murder dream and one other type of dream I wake up for a moment convinced it really happened. One time this lasted for a week until I finally remembered a detail about this false dream memory that just could not have happened in real life. Even still thinking about it I know these dreams arent real but I get this twinge of like "what if I suppressed it why are the feelings so real". Another time I woke up and immediately started drafting a message to someone I trusted about "what id done" before snapping out of it. Im not trying to direct this anywhere I factually have not killed anyone, or il be able to say that in like a week its funny always in the days following the dream even though I know I could not have killed someone like the dream wont make sense all the way it somehow will feel like I did though. I dont feel like I feel guilt exceptionally stronger than other emotions but maybe I do and thats why? Im not sure. I guess im just curious why this specific dream when i have many about other real life feelings or emotions and circumstances will be so convincing il think it was an actual memory not just for a moment but sometimes for days.
Its also always been a fascination for me in movies and shows and art, not murder but the moment a character sort of realizes they have done some ireedemable bad and cant undo it or go back and have maybe even ruined their life. I dont sympathize with them and whatever they have done but I strongly empathize with the panic guilt disgust and fear. This may be because of the dreams though ive had them since I was a kid.
