There I propose a way of verifying the manifestation of a dream by prediction and verification or falsification. Since the overall plot of a dream manifests at various times, from the dream day to the second day, stretching out for years at times as Barnsley's nightmare demonstrates, I was looking for an element of the dream that would invariably manifest on the dream day, which is the waking phase that follows the dream. ...the dream is a coin with two sides, one of which outlines the everyday concerns while the other delineates the sexual state and consequent erotic behaviour of the dreamer. ...it took thirty years before it was revealed to him in a dēja vu that this strange 'boat', which turned out to be the famous S-wing plane, would be his own brainchild and materialisation of his childhood dream (Inglis, 1987).
