The action of the hean on the other systems is obvious, and the influence of emotions on the organs is also becoming obvious. What is not so well established is the importance of the feedback occurring when we gain insight into our own functioning through understanding a dream. Although our being is already a self regulating system, the ability to turn consciousness inwards to make clear aspects of unconscious function appears to increase the efficiency of self regulation. This is shown in the first example of reptiles, lizards, snakes, where David finds a long-standing neck pain and goes through insight into its cause. In this way wc might be seen as a conscious organism which not only reprogrammes mental patterns or habits, but to some extent can renovate or change body efficiency as well.
