This concern between dreams and reality is a discussion of relative perceptions and the shows the contrast of Mysticism and Rationalism. Many times we see Zhuangzi try to explain reality as best he can. However he always comes to a point where after everything is said, there still exists that which cannot be explained.There is a force or existence beyond our world that we cannot conceive of and that does not fit into our physical or mental reality. It is the Mystical existence that, like Relativity, qualifies every statement. We speak of life and death as constructs of our physical world but there exists something beyond that. Zhuangzi says “Life and death are all powerful, but they cannot affect the soul. Heaven and earth may collapse, but that will remain. These are things of the physical world. They can be destroyed but the mystical remains. How is this so: From the point of view of difference.” Here we see that even the Mystical barrier is relative.
