However, “the object to be rediscovered is not the lost object, but its substitute by displacement; the lost object is the object of self-preservation, of hunger, and the object one seeks to re-find in sexuality is an object displaced in relation to that first object.” This initial scene of fantasy is created out of the frustrated infants’ deflection away from the instinctual need for milk and nourishment towards a phantasmization of the mothers’ breast, which is in close proximity to the instinctual need. Now bodily pleasure is derived from the sucking of the mother's breast itself. The mouth that was the original source of nourishment is now the mouth that takes pleasure in its own sucking. This substitution of the breast for milk and the breast for a phantasmic scene represents a further level of mediation which is increasingly psychic. The child cannot experience the pleasure of milk without the psychic re-inscription of the scene in the mind. “The finding of an object is in fact a re-finding of it.” It is in the movement and constant restaging away from the instinct that desire is constituted and mobilized. A similarly positive view of fantasy was taken by Sigmund Freud who considered fantasy () a defence mechanism. He considered that men and women "cannot subsist on the scanty satisfaction which they can extort from reality. 'We simply cannot do without auxiliary constructions,' as Theodor Fontane once said ... [without] dwelling on imaginary wish fulfillments." As childhood adaptation to the reality principle developed, so too "one species of thought activity was split off; it was kept free from reality-testing and remained subordinated to the pleasure principle alone. This activity is "fantasying" ... continued as "day-dreaming"." He compared such phantasising to the way a "nature reserve preserves its original state where everything ... including what is useless and even what is noxious, can grow and proliferate there as it pleases." Daydreams for Freud were thus a valuable resource. "These day-dreams are cathected with a large amount of interest; they are carefully cherished by the subject and usually concealed with a great deal of sensitivity ... such phantasies may be unconscious just as well as conscious." He considered these fantasies to include a great deal of the true constitutional essence of a personality, and that the energetic man "is one who succeeds by his efforts in turning his wishful phantasies into reality," whereas the artist "can transform his phantasies into artistic creations instead of into symptoms ... the doom of neurosis."
