repression are of themselves of an infantile origin, as we have learned
from the psychological investigation of the neuroses. I should like,
therefore, to withdraw the opinion previously expressed that it is
unimportant whence the dream-wish originates, and replace it by another,
as follows: _The wish manifested in the dream must be an infantile one_.
In the adult it originates in the Unc., while in the child, where no
separation and censor as yet exist between Forec. and Unc., or where
these are only in the process of formation, it is an unfulfilled and
unrepressed wish from the waking state. I am aware that this conception
cannot be generally demonstrated, but I maintain nevertheless that it
can be frequently demonstrated, even when it was not suspected, and that
it cannot be generally refuted.

The wish-feelings which remain from the conscious waking state are,
therefore, relegated to the background in the dream formation. In the
dream content I shall attribute to them only the part attributed to the
material of actual sensations during sleep. If I now take into account
those other psychic instigations remaining from the waking state which
are not wishes, I shall only adhere to the line mapped out for me by
this train of thought. We may succeed in provisionally terminating the
sum of energy of our waking thoughts by deciding to go to sleep. He is a
good sleeper who can do this; Napoleon I. is reputed to have been a
model of this sort. But we do not always succeed in accomplishing it, or
in accomplishing it perfectly. Unsolved problems, harassing cares,
overwhelming impressions continue the thinking activity even during
sleep, maintaining psychic processes in the system which we have termed
the foreconscious. These mental processes continuing into sleep may be
divided into the following groups: 1, That which has not been terminated
during the day owing to casual prevention; 2, that which has been left
unfinished by temporary paralysis of our mental power, _i.e._ the
