The French version of Kafka's book describes the sense of liberation that the monstrous cockroach has when he looks out the window, at the same time complaining of more and more intense myopia. In the metamorphosis an autistic fantasy is represented, replete with primary process elements. The fact that Grete, the sister, takes care of him, as she is the only member of the family who understands him, is based on feminine identification. During the metamorphosis the identification is masochistically complete and thinking the only ego function that remains. But the thoughts are not quite realistic and appropriate; they show a parasitic and clinging quality, especially when the sister turns her back on him. Castration anxiety related to a masturbatory fantasy with prominent pregenital roots is also evident. All these features account for the mixture of nostalgia, repugnance, and an indefinable sinister sensation that pervades the story.
