ontent. First of all came the
little episode from the time of my courting, of which I have already
spoken; the pressure of a hand under the table gave rise in the dream to
the "under the table," which I had subsequently to find a place for in
my recollection. There was, of course, at the time not a word about
"undivided attention." Analysis taught me that this factor is the
realization of a desire through its contradictory and related to the
behavior of my wife at the table d'hote. An exactly similar and much
more important episode of our courtship, one which separated us for an
entire day, lies hidden behind this recent recollection. The intimacy,
the hand resting upon the knee, refers to a quite different connection
and to quite other persons. This element in the dream becomes again the
starting-point of two distinct series of reminiscences, and so on.

The stuff of the dream thoughts which has been accumulated for the
formation of the dream scene must be naturally fit for this application.
There must be one or more common factors. The dream work proceeds like
Francis Galton with his family photographs. The different elements are
put one on top of the other; what is common to the composite picture
stands out clearly, the opposing details cancel each other. This process
of reproduction partly explains the wavering statements, of a peculiar
vagueness, in so many elements of the dream. For the interpretation of
dreams this rule holds good: When analysis discloses _uncertainty_, as
to _either_--_or_ read _and_, _taking_ each section of the apparent
alternatives as a separate outlet for a series of impressions.

When there is nothing in common between the dream thoughts, the dream
work takes the trouble to create a something, in order to make a common
presentation feasible in the dream. The simplest way to approximate two
dream thoughts, which have as yet nothing in common, consists in making
such a change in the actual expression of one idea as will meet a slight
responsive recasting in the form of the other idea. The process is
analogous to that of rhyme, when consonance supplies the desired common
factor. A good deal of the dream work consists in the creation of those
frequently very witty, but often exaggerated, digressions. These vary
from the common presentation in the dream content to dream thoughts
which are as varied as are the causes in form and essence which give
rise to them. In the analysis of our example of a
