This notion fits in well with psychoanalytic (a theory does not have to be correct to be productive)ideas of the unconscious such as those presented by Fritz Kunkel in the forties and fifties. They found the source of creativity to be the "preconscious" (i call it unlabeled awareness --perhaps it is where mystics go to connect with the universe?) Where the preconscious touches the unconscious artistic creativity is said to occur, where the preconscious touches the conscious mind scientific creativity occurs. i think there is definitely something to it.
