My fiancé talks in his sleep...😂😂😂TMI

The other night, (it was very late, probably around 11:30 PM) and I had just gotten off of work (I work as a nurse aide in a retirement home) and I come home to find my fiancé fast asleep. I tried slipping into bed with him and not waking him. At first I thought I woke him up, but it was just him talking in his sleep. The next few moments we'lre followed by me hysterically laughing.
"...Feels so good babe...don't stop..." 
Followed by various sex noises, and including my name a lot lmao.
"...I came..." 
He was having a wet dream about us! 😂 I've been with my fiancé for almost 4 years now and I have never heard that come out of his mouth when he sleeps. The next morning, I asked him if he slept well, and he said he did! I also asked him if he could remember what he was dreaming about, and he said he didn't remember dreaming at all, but when I had told him what I heard, he thought it was pretty funny too. It was super flattering, really. 
Just wondering if this has happened to any of you and your fiancé, or something similar?😂😂
