Rich Serial Killer

I believe I was with a bunch of random friends in my life (like GR, HG, AJ), but I can’t tell if they were supposed to be family or just friends in my dream. I think both. We were very close. Anyway, we were all in this huge mansion that we would be living in. However, over the course of this dream, a serial killer tried to kill each of us like three times. Each time I had to hide in the house, going through mazes of halls, doors, trap doors, ladders, and steps (with light wood and white paint) to find places to hide. At one point, the serial killer (late 20s guy dressed in all black) found me. I kind of asked him to just put me out of my misery. He said, instead, he would make me feel pain for a while but it would only be a small amount. He took a small knife and took my right hand, flipping it so my palm stuck up. He slowly began to jab the knife into my palm. I winced. It didn’t hurt that badly, but blood was beginning to ooze out of my palm. I decided I could take it, because A) if I ran away, he’d probably actually kill me, and B) the longer this went on, the more time my siblings/friends had to escape (I think the serial killer had a partner though). I think my siblings/friends came to rescue me. I remember being outside the mansion as police showed up. We all huddled together. Like I said, this happened like three times. I just had to keep exploring the house with my friends and finding places to hide. That was the only time I was caught though.
