anything about being beaten up?

ok usualy I never remember my dreams. But some days ago, I had this dream and it was SO realistic it freaked me out...

I was walking down the road to get somewere, and I was late. I was at a camp or something. I was with 2 other guys that were just as late as I was. Then, they randomly started insulting me and I did my best to just ignore them, but the first one said something that really pissed me off, and then, I punched him. I was going for a second punch when something hit me and made me fall. I realised I had forgotten the second guy. -cut in: Now this is strange. I think I got in a fight like 3 times since I have been to school. No matter how bad I was hurt or how much I was falling, I always put myself up to face back the person I was fighting with.-
So I was on the ground, and it didn't really felt like me. Why wasen't I getting up? The guys started kicking me and I got a very hard kick in the ribs. When I woke up I was allready crying and most of my body was stiff. I couln'd move and were I had been kicked in the ribs I felt something strange, like it didn't hurt, but... idk. I think the best word to describe that is that it stinged.

Anyway. I spoke to my mom, and she said mabey it was a past life thingy. But I am not sure, and I think it means something else.
Any ideas?
