Goethe said of Lichtenberg: “Where he cracks a joke, there lies a concealed problem.” Similarly we can affirm of these passages cited from my book: back of every error is a repression. More accurately stated: the error conceals a falsehood, a disfigurement which is ultimately based on repressed material. In the analysis of the dreams there reported, I was compelled by the very nature of the theme to which the dream thoughts related, on the one hand, to break off the analysis in some places before it had reached its completion, and on the other hand, to remove an indiscreet detail through a slight disfigurement of its outline. I could not act differently, and had no other choice if I was at all to offer examples and illustrations. My constrained position was necessarily brought about by the peculiarity of dreams, which give expression to repressed thoughts, or to material which is incapable of becoming conscious. In spite of this it is said that enough material remained to offend the more sensitive souls. The disfigurement or concealment of the continuing thoughts known to me could not be accomplished without leaving some trace. What I wished to repress has often against my will obtruded itself on what I have taken up, and evinced itself in the matter as an unnoticeable error. Indeed, each of the three examples given is based on the same theme: the errors are the results of repressed thoughts which occupy themselves with my deceased father. (_ad a_) Whoever reads through the dream analysed on page 361 will find some parts unveiled; in some parts he will be able to divine through allusions that I have broken off the thoughts which would have contained an unfavourable criticism of my father. In the continuation of this line of thoughts and memories there lies an annoying tale, in which books and a business friend of my father, named _Marburg_, play a part; it is the same name the calling out of which in the southern railway-station had aroused me from sleep. I wished to suppress this Mr. _Marburg_ in the analysis from myself and my readers: he avenged himself by intruding where he did not belong, and changed the name of Schiller’s birthplace from _Marbach_ to _Marburg_.
