What happens when you sleep

Yesterday we drove to Orem to spend time with friends and see an Orem Owlz Baseball game.
After the game James was riding on Dave's shoulders. Here is the conversation.

James: I'm tired.

Dave: Okay go to sleep

James: Not here, I am going to get in the car close my eyes, be invisable, then be asleep in my bed.

Because isn't that how it goes for 4 year olds. No matter what where you fall asleep,like magic, you always wake up in your own bed.
