into the part played by the wish-fulfillment in the dream, and into the
significance of the waking thoughts continued in sleep.

It is in fact the wish-fulfillment that has already induced us to
separate dreams into two groups. We have found some dreams that were
plainly wish-fulfillments; and others in which wish-fulfillment could
not be recognized, and was frequently concealed by every available
means. In this latter class of dreams we recognized the influence of the
dream censor. The undisguised wish dreams were chiefly found in
children, yet fleeting open-hearted wish dreams _seemed_ (I purposely
emphasize this word) to occur also in adults.

We may now ask whence the wish fulfilled in the dream originates. But to
what opposition or to what diversity do we refer this "whence"? I think
it is to the opposition between conscious daily life and a psychic
activity remaining unconscious which can only make itself noticeable
during the night. I thus find a threefold possibility for the origin of
a wish. Firstly, it may have been incited during the day, and owing to
external circumstances failed to find gratification, there is thus left
for the night an acknowledged but unfulfilled wish. Secondly, it may
come to the surface during the day but be rejected, leaving an
unfulfilled but suppressed wish. Or, thirdly, it may have no relation to
daily life, and belong to those wishes that originate during the night
from the suppression. If we now follow our scheme of the psychic
apparatus, we can localize a wish of the first order in the system
Forec. We may assume that a wish of the second order has been forced
back from the Forec. system into the Unc. system, where alone, if
anywhere, it can maintain itself; while a wish-feeling of the third
order we consider altogether incapable of leaving the Unc. system. This
brings up the question whether wishes arising from these different
