ABSTRACT
A young man who was in psycho-analytical treatment with the author had noticed since early childhood that his mother had an intimate extra-marital relationship with a man. In connection with this fact he had typical phantasies on the pattern of the Hamlet story: that the mother together with her lover would kill his father. Whilst the whole family were at dinner the mother related a peculiar dream she had had the previous night. A strange man had mocked at her and had derided her abilities and character. The story of his mother's dream had aroused author's patient's attention and he had understood at once that the stranger could have been none other than his father, who the mother, together with her lover, threw out: that is to say, did away with him. He rightly concluded that his mother's phantasy was concerned with the same crime as his own earlier phantasies.
