That the dream has at its disposal recollections which are inaccessible to the waking state is such a remarkable and theoretically important fact that I should like to urge more attention to it by reporting several other “Hypermnesic Dreams.” Maury[48] relates that for some time the word Mussidan used to occur to his mind during the day. He knew it to be the name of a French city, but nothing else. One night he dreamed of a conversation with a certain person who told him that she came from Mussidan, and, in answer to his question where the city was, she replied: “Mussidan is a principal country town in the Département de La Dordogne.” On waking, Maury put no faith in the information received in his dream; the geographical lexicon, however, showed it to be perfectly correct. In this case the superior knowledge of the dream is confirmed, but the forgotten source of this knowledge has not been traced. Jessen[36] tells (p. 55) of a quite similar dream occurrence, from more remote times. Among others we may here mention the dream of the elder Scaliger (Hennings, _l.c._, p. 300), who wrote a poem in praise of celebrated men of Verona, and to whom a man, named Brugnolus, appeared in a dream, complaining that he had been neglected. Though Scaliger did not recall ever having heard of him, he wrote some verses in his honour, and his son later discovered at Verona that a Brugnolus had formerly been famous there as a critic. Myers is said to have published a whole collection of such hypermnesic dreams in the _Proceedings of the Society for Psychical Research_, which are unfortunately inaccessible to me. I believe every one who occupies himself with dreams will recognise as a very common phenomenon the fact that the dream gives proof of knowing and recollecting matters unknown to the waking person. In my psychoanalytic investigations of nervous patients, of which I shall speak later, I am every week more than once in position to convince my patients from their dreams that they are well acquainted with quotations, obscene expressions, &c., and that they make use of these in their dreams, although they have forgotten them in the waking state. I shall cite here a simple case of dream hypermnesia because it was easy to trace the source which made the knowledge accessible to the dream. A patient dreamed in a lengthy connection that he ordered a “Kontuszówka” in a café, and after reporting this inquired what it might mean, as he never heard the name before. I was able to answer that Kontuszówka was a Polish liquor which he could not have invented in his dream, as the name had long been familiar to me in advertisements. The patient would not at first believe me, but some days later, after he had realised his dream of the café, he noticed the name on a signboard at the street corner, which he had been obliged to pass for months at least twice a day.
