Internal observations and hallucinations

The capability of deep observation must be one of the most important human values. The human soul seems to have many layers! I believe that each layer has the power to observe what goes on in the layers below it. It seems that as we move further up the layers the power of observation increases! If that were not the case, i.e. if the power of objective observation was not used, how could the “master hero of mind games” John Nash have noticed his own hallucinations? Remember that he said “If what I see were reality it would grow old with me”.
