Dream About Mansion Murder

I was inside some sort of mansion with my family. I do not remember any of why I did what I’m about to say, but I knew it was a planned thing that my family was in on, or at least knew about. Anyways, I sneaked around the mansion with a fairly big knife that I got from the kitchen, and my goal was to murder the entire family that had been living there. I can only remember one of the murder parts; I was upstairs in a bedroom, hiding behind a stroller or something. I was spying on someone that I referred to as ‘the assistant’, and he was just sitting on the bed with his phone in hand whilst talking to the supposed dad of the house, who was a few feet away from him. I can’t remember what they were talking about, but it was some casual conversation about either money or the mansion. The owner (implied father) walked around the corner to check on his mom, I’m guessing (she was an old lady, not in the best health condition due to her age), and that’s when I went for the assistant. After that, I checked up on his phone, and I don’t think I found anything useful on there. Next was the owners mom, then the owner himself. I can’t remember any of the other murders. Anyways, after the fact, I went back to my family who was chilling in the living room. I remember saying that the only person I actually felt bad about killing was the assistant, because he seemed like a nice guy. The end
