Freud formulated the concept of retrogressive screen memories in 1897 to describe memories of past events which unconsciously portray contemporary situations. He used this concept at several points in his self-analysis and in the disguised autobiographical paper “Screen memories” (1899). The 1899 paper on screen memories contains contradictions and incoherences. Freud’s correspondence allows us to reconstruct what may be the immediate triggers for Freud’s recollections of the screen memory of the meadow with the yellow flowers described in 1899. Freud’s theory of retrogressive screen memories seems to have been formulated specifically in order to reinterpret the data previously explained by the “seduction theory” of 1896. Freud never used the theory of retrogressive screen memories to reinterpret this data. It is suggested that if Freud had done this he would have been forced to conclude that his patients unconsciously regarded his psychotherapeutic approach as a form of seduction. Freud’s screen memory of the meadow with the yellow flowers may have provided a source of countertransference in his treatment of the Rat Man en the Wolf Man.
