ght possibly
think that the condensation and compromise formation is effected only in
the service of regression, when occasion arises for changing thoughts
into pictures. But the analysis and--still more distinctly--the
synthesis of dreams which lack regression toward pictures, _e.g._ the
dream "Autodidasker--Conversation with Court-Councilor N.," present the
same processes of displacement and condensation as the others.

Hence we cannot refuse to acknowledge that the two kinds of essentially
different psychic processes participate in the formation of the dream;
one forms perfectly correct dream thoughts which are equivalent to
normal thoughts, while the other treats these ideas in a highly
surprising and incorrect manner. The latter process we have already set
apart as the dream-work proper. What have we now to advance concerning
this latter psychic process?

We should be unable to answer this question here if we had not
penetrated considerably into the psychology of the neuroses and
especially of hysteria. From this we learn that the same incorrect
psychic processes--as well as others that have not been
enumerated--control the formation of hysterical symptoms. In hysteria,
too, we at once find a series of perfectly correct thoughts equivalent
to our conscious thoughts, of whose existence, however, in this form we
can learn nothing and which we can only subsequently reconstruct. If
they have forced their way anywhere to our perception, we discover from
the analysis of the symptom formed that these normal thoughts have been
subjected to abnormal treatment and _have been transformed into the
symptom by means of condensation and compromise formation, through
superficial associations, under cover of contradictions, and eventually
over the road of regression_. In view of the complete identity found
between the peculiarities of the dream-work and of the psychic activity
forming the psychoneurotic symptoms, we shall feel justified in
transferring to the dream the conclusions urged upon us by hysteria.

From the theory of hysteria we borrow the proposition that _such an
abnormal psychic elaboration of a normal train of thought takes place
only when the latter has been used for the transference of an
unconscious wish which dates from the infantile life and is in a state
of repression_. In accordance with this proposition we have construed
the theory of the dream on the assumption that the actuating dream-wish
invariably orig
