In the wee hours

Me, dreaming about back-seat driving for Frank: Train!

Frank, coming up from a deep sleep: What?

Me, awake enough to know I was talking in my sleep but not yet enough to be coherent: There was a train coming.

Frank, struggling to make sense of it all: What?

Me: It's okay, I was talking in my sleep.

I never got back to sleep, so that was the start of my day. It's funny now.
