I had a dream last night that I was in a different life, What does this mean?

In my dream I woke up in a different life. I was in a different house, bed, room etc. I looked in a mirror and realized I had my ashy blonde hair color, but I had a thick, bright, golden blonde highlights. I also had darker brown eyes than I have now, which are a very light almost one tone brown. I looked at my face, which in real life I have lots of acne, but not extremely severe, and my face was flawless and tanner. I went downstairs and I had the same mom, but she was thinner and also had blonde hair. had a brother. He had shortish blonde hair and he kind of looked like KC from Degri, but had more defined features. He was also, unlike all of us, extremely tall about 5' 11". He was in a band and was going to be in a battle of the bands competition. I still wore what I usually wear, band tee's and jean shorts and stuff like that, and I liked everything I like, rock music, Andy Six, love, a guy named Drew. I woke up then fell asleep again and we were all there and at a place where music would be played and we were sitting on bleachers and my brother walked by. Some girl I apparently new said he was hot and I said yea I know if we weren't related I'd have the biggest crush on him. My friend Kate was sitting next to me and looked confused. I took her over to this closet and told her everything about waking up in a new life and she told me just to go with it so I continued to. The battle of that bands started and we listened and jammed to music. Before my brothers we went backstage and I jumped on his back and we talked before he went on, so obviously we had a good relationship. His hair was a little longer though, almost shoulder length, but not quite there, and we went back to hear him and his band play. They ended up winning and he left on a trip to a bigger competition.We talked to him before he left and Kate told him he better come home to us soon, so maybe we were sisters. Next I was in my room again, but Kate was there too in another room, and I heard a noise and it ended up being my brother coming home. Me and Kate hugged him and we talked, but I don't remember what about I think his trip. I woke up after that, What does my dream mean?
