Is it normal to have dreams of being the opposite gender?

I mean...in this dream...I was a girl...and I was so happy...and yet all I was doing was making chocolate milk.

I remember this dream more vividly than the others...I was in my kitchen, the glass I was using was a tall and wide one (I could give you a picture of the actual glass, we have tons of them and it's my favorite type of glass out of all the ones in the pantry cause it holds the most stuff. But that's not important.) I was using that old Ovaltine chocolate milk powder, you know, the one that no one cares about anymore cause they use Nesquik cause they're the exact same thing except Nesquik has a bunny. It was a large container, and it was about 9/10ths full. I was using a spoon that may have been slightly larger than a tablespoon...

And usually all I remember in dreams is little 3 second clips around whatever reminders I write on my sticky notes. I had this dream 2 hours ago and I haven't written anything down and I still remember it almost as though it really happened...
