What does it mean to dream of someone attempting to molest you?

I had a dream where I was 8 years old and I was playing in a primary school (elementary school) Australian Rules Football team. The little kids, including me went to the changerooms to change out of our sports uniforms. The coach came up behind me and started to try to touch me inappropriately. It made me feel uncomfortable. He didn't get very far before I suddenly took on a consciousness or awareness as if I was current self in my 8 year old body (I am 27 years old) and I felt a righteous anger. I basically gave him the biggest shock of his life by lecturing and verbally pulling him apart about on how many levels his behaviour was wrong - he never got any further. He was shocked and stopped moving entirely. I also told him I would be watching him as I grow up, and that if ever he attempts to molest me or anyone else, that I would deal with him. It was as if I was part of some sort of group or something that punishes wrong-doers and that I had the awareness of someone well beyond an 8 year old despite my age. I also gave the coach a strange order where he could also not touch his own face or mouth - almost like a punishment or atonement for what he had possibly done to others before he tried anything on me. The dream skipped to several years later, and he was older. He had grown a massive grey beard because he had not shaved his face (implied he had followed exactly what I had told him to all this time).
