Is it normal to dream that you are the opposite sex?

I didn't really do anything that bad but I did have two girls all over me. it was the weirdest feeling, or i think they were girls. I think slowly everything started to be transgendered. but I do know I was a guy. which hasn't been the first time I was a guy in my dream.
(I wake up in the morning though glad I have a vagina. lol )
