I had a weird dream

So basically I don't know what my motive/intent was but I killed my best friend's mom and the cops never found her so I was comforting her while getting rid of every piece of evidence. At some point I even forgot I murdered her mom (gaslighted myself lmao), so I continued living my life and my bsf never got to know. Flash forward I'm now getting married to Chris Hemsworth I'm alone in the changing room admiring myself in the mirror but then my reflection starts speaking to me telling me they know what I did. Before I know it my reflection hopped out of the mirror and was like now literally in front of me. Turns out this second me was the personality my brain split after I killed my bsf mom, and they developed a personality of themselves that was able to manifest into a separate entity. It started choking me out of nowhere, and it was really creepy because I slowly started remembering my crime, as I could hear the past screams of her mom. I ended up stabbing myself(?) and afterwards it was lowkey giving "Married in red" vibes because I walked to the alter in a bloody gown. Everyone screamed, but Chris just smiled and asked if I atone? (with this weird Scottish accent)
