As the third of the peculiarities of the dream content, we have cited from all the authors (except Robert) the fact that impressions from the earliest times of our lives, which seem not to be at the disposal of the waking memory, may appear in the dream. It is, of course, difficult to judge how often or how seldom this occurs, because the respective elements of the dream are not recognised according to their origin after waking. The proof that we are dealing with childhood impressions must thus be reached objectively, and the conditions necessary for this happen to coincide only in rare instances. The story is told by A. Maury,[48] as being particularly conclusive, of a man who decided to visit his birthplace after twenty years’ absence. During the night before his departure, he dreams that he is in an altogether strange district, and that he there meets a strange man with whom he has a conversation. Having afterward returned to his home, he was able to convince himself that this strange district really existed in the neighbourhood of his home town, and the strange man in the dream turned out to be a friend of his dead father who lived there. Doubtless, a conclusive proof that he had seen both the man and the district in his childhood. The dream, moreover, is to be interpreted as a dream of impatience, like that of the girl who carries her ticket for the concert of the evening in her pocket (p. 110), of the child whose father had promised him an excursion to the Hameau, and the like. The motives explaining why just this impression of childhood is reproduced for the dreamer cannot, of course, be discovered without an analysis. One of the attendants at my lectures, who boasted that his dreams were very rarely subject to disfigurement, told me that he had sometime before in a dream seen _his former tutor in bed with his nurse_, who had been in the household until he was eleven years old. The location of this scene does not occur to him in the dream. As he was much interested, he told the dream to his elder brother, who laughingly confirmed its reality. The brother said he remembered the affair very well, for he was at the time six years old. The lovers were in the habit of making him, the elder boy, drunk with beer, whenever circumstances were favourable for nocturnal relations. The smaller child, at that time three years old—our dreamer—who slept in the same room as the nurse, was not considered an obstacle.
