It is difficult to say where the borderline of play begins; necessarily so, for the unconscious product is the creation of a sportive fancy, of that psychic impulse out of which play itself arises. It is repugnant to the scientific mind to have serious dealings with this element of play, which on all sides loses itself in the vague. But it must be never forgotten that the human mind has for thousands of years amused itself with just this kind of game; it were therefore nothing wonderful if this historic past again compelled admission in dream to similar tendencies. The patient pursues in his waking life similar phantastic tendencies about figures, as is seen in the fact already mentioned of the celebration of the 100th birthday. Their presence in the dream therefore need not surprise us. In a single example of unconscious determination exact proofs are often lacking, but the sum of our experiences entitles us to rely upon the accuracy of the individual discoveries. In the investigation of free creative phantasy we are in the region, almost more than anywhere else, of broad empiricism; a high measure of discretion as to the accuracy of individual results is consequently required, but this in nowise obliges us to pass over in silence what is active and living, for fear of being execrated as unscientific. There must be no parleying with the superstition-phobia of the modern mind; for this itself is a means by which the secrets of the unconscious are kept veiled. It is of special interest to see how the problems of the patient are mirrored in the unconscious of his wife. His wife had the following dream: She dreamt, and this is the whole dream: "_Luke_ 137." The analysis of the number gives the following. To 1 she associates: The doctor has another child. He had three. If all her children were living she would have 7; now she has only 3 - 1 = 2. But she desires 1 + 3 + 7 = 11 (a twin number, 1 and 1), which expresses her wish that her two children had been pairs of twins, for then she would have reached the same number of children as the doctor. Her mother once had twins. The hope of getting a child by her husband is very precarious; this had for a long time turned her ideas in the unconscious towards a second marriage. Other phantasies pictured her as "done with," _i.e._ having reached the climacteric at 44. She is now 33 years old, therefore in 11 years she will have reached her 44th year. This is an important period as her father died in his 44th year. Her phantasy of the 44th year contains the idea of the death of her father. The emphasis on the death of her father corresponds to the repressed phantasy of the death of her husband, who is the obstacle to a second marriage. At this place the material belonging to the dream "_Luke_ 137" comes in to solve the conflict. The dreamer is, one soon discovers, in no wise well up in her Bible, she has not read it for an incredible time, she is not at all religious.
