This knowledge has a bearing on another of the problems which up to the present have proved insoluble. You will remember the astonishment caused by our discovery that dreams have their origin in actively evil or in excessive sexual desires, which have made both the dream-censorship and dream-distortion necessary. Supposing now that we have interpreted a dream of this sort, and the circumstances are specially favourable in that the dreamer does not quarrel with the interpretation itself, he does nevertheless invariably ask how any such wish could come into his mind, since it seems quite foreign to him and he is conscious of desiring the exact opposite. We need have no hesitation in pointing out to him the origin of the wish he repudiates: these evil impulses may be traced to the past, often indeed to a past which is not so very far away. It may be demonstrated that he once knew and was conscious of them, even if this is no longer so. A woman who had a dream meaning that she wished to see her only daughter (then seventeen years old) lying dead found, with our help, that at one time she actually had cherished this death-wish. The child was the offspring of an unhappy marriage, which ended in the speedy separation of husband and wife. Once when the child was as yet unborn the mother, in an access of rage after a violent scene with her husband, beat her body with her clenched fists in order to kill the baby in her womb. How many mothers who to-day love their children tenderly, perhaps with excessive tenderness, yet conceived them unwillingly and wished that the life within them might not develop further; and have indeed turned this wish into various actions, fortunately of a harmless kind. The later death-wish against beloved persons, which appears so puzzling, thus dates from the early days of the relationship to them.
