Dream about assisted suicide

Hello, I had the most awful dream today. My friend from real life was in it. She was as miserable as she is in the real life. Rude and hateful of EVERYTHING around her, she had decided she had enough of it. We were laying on some kind of sofa or bed, she was laying on my stomach when she handed me the box cutter. She said I must be the one to do it, I must be the one to cease her suffering, yet she wasn't crying when she told me so. She sounded.... Accepting of her fate. The atmosphere was very tense, almost nauseating and dark. I didn't want to do it, I didn't want to murder anybody; that's the part whe she started crying hysterically. I think the dream was almost lucid? I remember very real urge to puke, I can recall the precise stench of the room, I remember the raw panic I felt. Then I did it, because her yelling had grown overwhelming and almost scary. I've struck the blade in her forehead, which began bleeding rivers of blood almost immediately. She kept screaming I should do more. I took the blade and stabbed her abdomen, to which, a white substance (almost like tripe sausage filling) started spurting out in stiff ropes. The worst thing was the smell, incredibly strong stench of blood and rotten meat filled the air. She kept thrashing around, smearing the mess everywhere as she was dying. Then I woke up, in the middle of the night and really sweaty. I could hardly look her in the eye the whole day after that, although I didn't tell her why. The only relevant thing is; I'm starting to dislike her due to her downright pathetic and hateful personality, but I'd never wish her any harm. That's why I'm concerned about this.

Big thanks to anyone who's willing to look into it <3
