k flowed furnishes a quite definite suggestion. Here also
the above mentioned "from behind" probably gets a meaning.

The circumstance that the dream has, as it were, two faces, with one that
it openly exposes to view, implies that a distinction must be made between
the manifest and the latent material. The openly exposed face is the
manifest dream content (as the wording of the dream report represents the
dream); what is concealed is the latent dream thoughts. For the most part
a broad tissue of dream thoughts is condensed into a dream. A part of the
dream thoughts (not all) belongs regularly to the titanic elements of our
psyche. The shaping of the dream out of the dream thoughts is called by
Freud the dream work. Four principles direct it, Condensation,
Displacement, Representability, and Secondary Elaboration.

Condensation was just now mentioned. Many dream thoughts are condensed to
relatively few, but therefore all the more significant, images. Every
image (person, object, etc.) is wont to be "determined" by several dream
thoughts. Hence we speak of multiple determination or "Overdetermination."

Displacement shows itself in the fact that the dream (evidently in the
service of distortion) pushes forward the unreal and pushes aside the
real; in short, rearranges the psychic values (interest) in such a way
that the dream in comparison with its latent thoughts appears as it were
displaced or "elsewhere centered."

As the dream is a perceptual representation it must put into perceptually
comprehensible form everything that it wants to express, even that which
is most abstract. The tendency to vividly perceptual or plastic expression
that is characteristic of the dream, corresponds accordingly to the
Representability.

To the Secondary Elaboration we have to credit the last polishing of the
dream fabric. It looks after the logical connection in the pictorial
material, which is created by the displacing dream work. "This function
(i.e., the secondary elaboration) proceeds after the manner which the poet
maliciously ascribes to the philosopher; with its shreds and patches it
stops the gaps in the structure of the dream. The result of its effort is
that the dream loses its appearance of absurdity and disconnectedness and
approaches the standard of a comprehensible experience. But the effort is
not always crowned with complete success." (Freud, "Traumdeutung," p.
330.) The secondary elaboration can be compared also to t
