What does this dream about rape mean?

In reality, I'm one of the leads in a school musical which opens tomorrow night. Last night, I dreamt that it was opening night and I was going into my changing room to get changed into my costume. A lot of other things in the dream had gone wrong (set, cast missing songs, forgetting choreography, etc.) Anyway, the dressing room was split into two hallways, one for boys and one for girls. I walked in and there were five boys, and three of them tried to rape me. I knew that if I walked into the dressing room to get changed, they'd rape me. So I yelled for a teacher at the school to come help me, and they backed off. But then the teacher didn't come and they started to gang up on me again, so I hollered louder and they left me alone.

Then, though, I was walking into a room and I knew that the guys who wanted to rape me were in the room nearby. So I walked into the room and saw a little kid on the verge of tears. It was the little brother of one of the kids so I walked into the room to protect him and locked the door. I tried to hold and protect the kid as the would-be rapists came in and fought for my life to get rid of them (my top priority was the kid) but then the rapists left because some authority figure came and saved us.

What's this mean? thanks!
