Strümpell[66] (p. 40): “The subject becomes more interesting when we remember how the dream sometimes brings forth, as it were, from among the deepest and heaviest strata which later years have piled upon the earliest childhood experiences, the pictures of certain places, things, and persons, quite uninjured and with their original freshness. This is not limited merely to such impressions as have gained vivid consciousness during their origin or have become impressed with strong psychic validity, and then later return in the dream as actual reminiscences, causing pleasure to the awakened consciousness. On the contrary, the depths of the dream memory comprise also such pictures of persons, things, places, and early experiences as either possessed but little consciousness and no psychic value at all, or have long ago lost both, and therefore appear totally strange and unknown both in the dream and in the waking state, until their former origin is revealed.” Volkelt[72] (p. 119): “It is essentially noteworthy how easily infantile and youthful reminiscences enter into the dream. What we have long ceased to think about, what has long since lost for us all importance, is constantly recalled by the dream.” The sway of the dream over the infantile material, which, as is well known, mostly occupies the gaps in the conscious memory, causes the origin of interesting hypermnestic dreams, a few of which I shall here report. Maury[48] relates (p. 92) that as a child he often went from his native city, Meaux, to the neighbouring Trilport, where his father superintended the construction of a bridge. On a certain night a dream transported him to Trilport, and he was again playing in the city streets. A man approached him wearing some sort of uniform. Maury asked him his name, and he introduced himself, saying that his name was C——, and that he was a bridge guard. On waking, Maury, who still doubted the reality of the reminiscence, asked his old servant, who had been with him in his childhood, whether she remembered a man of this name. “Certainly,” was the answer, “he used to be watchman on the bridge which your father was building at that time.”
