n by the
dominating end-occupation; or if an unconscious wish were made active
for other--possibly somatic--reasons and of its own accord sought a
transference to the psychic remnants not occupied by the Forec. All
three cases finally combine in one issue, so that there is established
in the foreconscious a stream of thought which, having been abandoned by
the foreconscious occupation, receives occupation from the unconscious
wish.

The stream of thought is henceforth subjected to a series of
transformations which we no longer recognize as normal psychic processes
and which give us a surprising result, viz. a psychopathological
formation. Let us emphasize and group the same.

1. The intensities of the individual ideas become capable of discharge
in their entirety, and, proceeding from one conception to the other,
they thus form single presentations endowed with marked intensity.
Through the repeated recurrence of this process the intensity of an
entire train of ideas may ultimately be gathered in a single
presentation element. This is the principle of _compression or
condensation_. It is condensation that is mainly responsible for the
strange impression of the dream, for we know of nothing analogous to it
in the normal psychic life accessible to consciousness. We find here,
also, presentations which possess great psychic significance as
junctions or as end-results of whole chains of thought; but this
validity does not manifest itself in any character conspicuous enough
for internal perception; hence, what has been presented in it does not
become in any way more intensive. In the process of condensation the
entire psychic connection becomes transformed into the intensity of the
presentation content. It is the same as in a book where we space or
print in heavy type any word upon which particular stress is laid for
the understanding of the text. In speech the same word would be
pronounced loudly and deliberately and with emphasis. The first
comparison leads us at once to an example taken from the chapter on "The
Dream-Work" (trimethylamine in the dream of Irma's injection).
Historians of art call our attention to the fact that the most ancient
historical sculptures follow a similar principle in expressing the rank
of the persons represented by the size of the statue. The king is made
two or three times as large as his retinue or the vanquished enemy. A
piece of art, however, from the Roman period makes use of more subtle
