Half asleep sex

So I'm 31 weeks pregnant and hubby works a ton so we haven't been having a lot of sex lately. The past month or so though I'll literally seduce him in my sleep and we'll have some of the best sex we've ever had! Like I've always talked in my sleep but I guess I'll start talking dirty to him while still asleep and by the time I'm actually partially awake I'm usually climbing on top of him. Does anyone else do this? We're both okay with it because like I said this has been some of the best sex we've ever had but it's just so weird to me that I initiate it when I'm not even awake. He did the same the other night I woke up to him grabbing my boobs and rubbing my ass but he wasn't even awake
