Human beings receive both physical and mental nourishment. As you grow, you are trained to express behavior that is ‘correct and good.’ Your more natural way of expressing yourself in behaviors that may have been classified as bad, can become repressed within the unconscious. Maybe you were exuberant when your family was not. This part of your nature does not go way, but continues to seek expression. Dreaming is a way for the psyche to express and integrate unprocessed qualities that you believe are not acceptable.
