what do women's wet dreams mean

I have orgasms in my sleep, what can be called “wet dreams.” When I dream something erotic (even if it’s just my husband and I having sex), not only do I become aroused, but I have actual orgasms. I would say I have several wet dreams a month. Now, I’m not complaining — it’s kind of awesome, to be honest! — but I want to know how common this is amongst women? Because I’ve never heard of women having wet dreams. Men, yes…women, no. Although, my own husband hasn’t ever had a wet dream. I find that strange, because I always thought that men are the only ones to have them. So what’s the deal?
