Dream About Performance And Accidental Injury

I can’t really remember how it started, so I’ll say what I can remember. I was in school and every few months there is a performance that random students do, it can be about anything (this is in the dream, we don’t do performances irl). Me and one of my friends were about to do a performance. We were gonna act out that one “I just killed my ex” song (super random lol). My friend had a fake knife that she would “stab” me with on the stage. The stage was decorated as a bedroom or a living room (I can’t really remember which one it was, but I think it was a bedroom). We did the whole performance without a problem, but after it I felt a pain in between my (right) shoulder and chest. It had only started hurting when I was with my other friends. I stretched my shirt’s collar area to see if anything was there, and there was a mark that was bleeding. It turned out my friend had somehow accidentally stab me a little bit. The end of the dream was basically her apology and us being confused on how that happened (because of the type of fake knife it was). The end :P
