of the latter or through pathological reinforcement of the unconscious
excitations, and this while the foreconscious is charged with energy and
the avenues to motility are open. The guardian is then overpowered, the
unconscious excitations subdue the Forec.; through it they dominate our
speech and actions, or they enforce the hallucinatory regression, thus
governing an apparatus not designed for them by virtue of the attraction
exerted by the perceptions on the distribution of our psychic energy. We
call this condition a psychosis.

We are now in the best position to complete our psychological
construction, which has been interrupted by the introduction of the two
systems, Unc. and Forec. We have still, however, ample reason for giving
further consideration to the wish as the sole psychic motive power in
the dream. We have explained that the reason why the dream is in every
case a wish realization is because it is a product of the Unc., which
knows no other aim in its activity but the fulfillment of wishes, and
which has no other forces at its disposal but wish-feelings. If we
avail ourselves for a moment longer of the right to elaborate from the
dream interpretation such far-reaching psychological speculations, we
are in duty bound to demonstrate that we are thereby bringing the dream
into a relationship which may also comprise other psychic structures. If
there exists a system of the Unc.--or something sufficiently analogous
to it for the purpose of our discussion--the dream cannot be its sole
manifestation; every dream may be a wish-fulfillment, but there must be
other forms of abnormal wish-fulfillment beside this of dreams. Indeed,
the theory of all psychoneurotic symptoms culminates in the proposition
_that they too must be taken as wish-fulfillments of the unconscious_.
Our explanation makes the dream only the first member of a group most
important for the psychiatrist, an understanding of which means the
solution of the purely psychological part of the psychiatric problem.
