Many of the characters or elements of our dreams act quite contrary to what we wish ourselves. This is why we often find it so difficult to believe all aspects of a dream are part of our own psyche. Some drives or areas of self do act or express despite what we consciously wish. These are named autonomous complexes. Recent research into brain activity shows that in fact the brain has different layers or strata of activity. These strata often act independently of each other or of conscious will. Sensing them, as one might in a dream, might feel like meeting an opposing will. Integration with these aspects of self can be gained.
