Writers and artists like painter etc can put their minds onto a piece of paper or a screen as of today's advancements in technology! And I believe every writer,sculpture etc needs a keen idea and basis to write or draw their work. Exploring of positive world is a very fantastic opportunity and if you being positive show your work to others they might get affected and move towards positive side of life.
And I do believe that if one close eyes he/she will see the spark of imagination in their subconscious mind.
So I think it's different according to different persons.
Great work ma'am
