Reverie and nature are often the groundwork of creative imagination of the artist.
"It is quite evident that a barrier must be cleared in order to escape the psychologists and enter into a realm which is not "auto-observant", where we ourselves no longer divide ourselves into observer and observed. Then the dreamer is completely dissolved in his reverie. His reverie is his silent life. It is that silent peace which the poet wants to convey to us."
Gaston Bachelard
