Dream of kids

I had a very unusual dream. This couples old house had become a place where kids thought it was funny to go and see if the tales they had heard were true. They would go and have sex at this house and a mans ghost would appear very angry and kill the guys. In my dream I was there but not in it I was just watching my dream it seemed. When the ghost appeared his face looked sad at first then when he realized what the kids were doing his face became very angry and he would start flying around really fast and messing stuff up and then he would kill the boys but never the girls. In my dream it was almost as if he could see me and wanted me to make them stop having sex in his home. I have never had a dream like this so I am just curious what it could possibly mean. I was not scared in my dream but sad and anxious like I needed to do something to help the ghost.
