My stomach, though not exactly empty or full (Content, let us say), is complaining, as it does once I reach a certain point of conciousness.
My neck is tingling, as if someone is watching me.
And my brain is tapping into the messages of the Universe again.
All the above are signs to get to sleep.
Oh, what messages? "Don't pee in the ocean." The big U is getting annoyed at that.
