ELI5: What is exactly happening in my brain/body when "I'm zoned out and don't feel like doing absolutely anything"?

Typically on a Sunday afternoon, for instance.

You're in a safe, undirected, hypnotic trance.

Your subconscious mind is still working in the background, watching out for fire, home invasions, and the like. 

Just as it is when you're zoned out driving to work and suddenly realize you have no memory of the ride with its eight stoplights along the way that you *must* have stopped for.

A directed trance is what you see at a comedy hypnosis show where volunteers are told what to do. Your conscious mind is zoned out but your subconscious has fun acting silly.
