Sleepy voices are cute in general.

I love my sleepy voice though.

I’m an air head when I’m sleepy.

Once I was in a big truck with my head on the window and I can’t remember it it was the  pulling in or taking a turn, I was so zonked.  And all you here is a CLUNK and me mumble “owwe”.  My head bounced off the window.  Everyone I was with laughed at me.  I laugh at me too though ha
