What is the purpose of sleep? Is it to replenish our body or is there a deeper meaning to the cycle of sleep? Why do we dream? John explains the difference between going to sleep in patterns and tightness, and going to sleep matching our being. In matching our being, there is a different kind of freshness when we wake up, having been washed, during sleep, through all of the depths of our being. Going to sleep can be one of the most awesome times of the day.
