Embarrassed in school

So today was my "annaversary" I guess. I've been with my bf for 11 months. And I'm on my period so no sex. And we're both EXTREMELY busy for it anyways. But I fell asleep right in the middle of class cause it was the morning and I was done with my test before anyone else. 
I forgot where I was in my sleep. So I started to have a VERY sexual dream about him. And it was really good. And I got really turned on. And my friend woke me up and knocked me off my chair. I woke up on the floor and was red in the face. 
She said I was talking/mumbling in my sleep. 
So I was extremely quiet the entire rest of class. When I saw him I told him. Then he laughed REALLY hard at me. He said he's happy I'm comfortable enough to tell him these things
