of the worry there need be no connection, nor was there one in any of
our examples.

We can now sharply define the significance of the unconscious wish for
the dream. It may be admitted that there is a whole class of dreams in
which the incitement originates preponderatingly or even exclusively
from the remnants of daily life; and I believe that even my cherished
desire to become at some future time a "professor extraordinarius" would
have allowed me to slumber undisturbed that night had not my worry about
my friend's health been still active. But this worry alone would not
have produced a dream; the motive power needed by the dream had to be
contributed by a wish, and it was the affair of the worriment to
procure for itself such wish as a motive power of the dream. To speak
figuratively, it is quite possible that a day thought plays the part of
the contractor (_entrepreneur_) in the dream. But it is known that no
matter what idea the contractor may have in mind, and how desirous he
may be of putting it into operation, he can do nothing without capital;
he must depend upon a capitalist to defray the necessary expenses, and
this capitalist, who supplies the psychic expenditure for the dream is
invariably and indisputably _a wish from the unconscious_, no matter
what the nature of the waking thought may be.

In other cases the capitalist himself is the contractor for the dream;
this, indeed, seems to be the more usual case. An unconscious wish is
produced by the day's work, which in turn creates the dream. The dream
processes, moreover, run parallel with all the other possibilities of
the economic relationship used here as an illustration. Thus, the
entrepreneur may contribute some capital himself, or several
entrepreneurs may seek the aid of the same capitalist, or several
capitalists may jointly supply the capital required by the entrepreneur.
