What does my dream mean?

last night I had a dream that I was with 3 female friends as we went to a boys house in a street that was very familiar to me. One of the girls advised me that the boy might say something to offend me due to something I had previously done ( no idea what this was ). As I stood at the door the boy opened it and instantly grabbed me and started burning my hair with a lighter whilst laughing. Then he turned to one of the other girls and tried to do the same to her. But the two remaining girls were laughing along with him, despite us screaming for help. As we hurried away there was all of a sudden another boy with him following us. The two boys were picking up dog poo and trying to chuck it at us. The fear in this dream was horrendous!!. Finally me and the girl found ourselves in a house with the parents of the 2 other girls who seemed angry with there daughters but not bothered enough to do anything about it. Then we all sat round a table having soup, but i could feel the embarrassment of us siting there with our hair all burned and also angry that we had to sit with these girls after none of them helping us! . . . . . . soo messed up i know but it makes absolutely no sense to me atall.
