having a dream as someone else?

A few nights ago i had a dream that i was a very thin black women. I was married and had a child. In the dream my husband was abusing me, I tried to escape but i never did. We were in a small bedroom where he tied me to our bed. He would kiss me and touch me, then he beat me. I woke up after the beating. It was a terrifying dream. I'm 14 and that's the first dream I've ever had as a different person. Does it mean anything? if so what? any help is appreciated! thank you!
