To give contours and relief to my dreams, I have to understand how life's characters and reality's landscapes appear to us with contours and relief. Because the dreamer's eyesight is not like the eyesight we use to see actual things. In dreams we do not, as in reality, focus equally on the important and unimportant aspects of an object. The dreamer sees only what's important. An object's true reality is only a portion of what it is; the rest is the heavy tribute it pays to physical matter for the right to exist in space. In like manner, certain phenomena that are palpably real in dreams have not reality in space. A real sunset is imponderable and transitory. A dreamed sunset is fixed  and eternal.
