A patient's phobic avoidance of the corners of buildings is analysed as the pretence of innocence whereby he could deny that he had ever seen the front of the building (the genitals of the mother). Behind this pretence he unconsciously indulged his fantasies of the forbidden incestuous desires to be found around the corner. This is compared with Feldman's interpretation of dreams of examinations and of missing trains as attempts to discharge incestuous genital drives behind a façade of painful affect.
