Is it normal to dream that i was licking my friend's (male) nipples?

I mean...it was a dream. Dreams can get pretty weird.

Yes, dreams can be convoluted. Sexual dreams rarely ever mean you actually want the person sexually.

Meh, I've had weirder dreams. Your brain likes to mix things up. I wouldn't worry about it.

It could be worse, you could have been licking a cat's nipples I guess.
