Freud on The realm of imagination

“The realm of imagination was seen to be a “reservation” made during the painful transition from the pleasure principle to the reality principle in order to provide a substitute for instinctual satisfactions which had to be given up in real life. The artist, like the neurotic, had withdrawn from an unsatisfying reality into this world of imagination; but, unlike the neurotic, he knew how to find a way back from it and once more to get a firm foothold in reality. His creations, works of art, were the imaginary satisfactions of unconscious wishes, just as dreams are; and like them they were in the nature of compromises, since they too were forced to avoid any open conflict with the forces of repression. But they differed from the asocial, narcissistic products of dreaming in that they were calculated to arouse sympathetic interest in other people and were able to evoke and to satisfy the same unconscious wishful impulses in them too.”
