"I believe that everyone, some time or other, dreams that he is reading papers, books, or letters; in which case the invention prompts so readily that the mind is imposed upon, and mistakes its own suggestions for the composition of another."

Essentially, in photography, I think on two levels: one emotional and the other technical. The emotional impact has to do with looking for something dramatic happening in the photograph, something that reaches out and touches somebody in some way. And the technical is having to do with composition and framing - light and dark, light and shadow.
