a scene which is
absolutely intolerable to him. This was the means used by one who was
troubled by a painful perineal abscess. He dreamt that he was on
horseback, and made use of the poultice, which was intended to
alleviate his pain, as a saddle, and thus got away from the cause of the
trouble. Or, as is more frequently the case, the external stimulus
undergoes a new rendering, which leads him to connect it with a
repressed desire seeking its realization, and robs him of its reality,
and is treated as if it were a part of the psychical matter. Thus, some
one dreamt that he had written a comedy which embodied a definite
_motif_; it was being performed; the first act was over amid
enthusiastic applause; there was great clapping. At this moment the
dreamer must have succeeded in prolonging his sleep despite the
disturbance, for when he woke he no longer heard the noise; he concluded
rightly that some one must have been beating a carpet or bed. The dreams
which come with a loud noise just before waking have all attempted to
cover the stimulus to waking by some other explanation, and thus to
prolong the sleep for a little while.

Whosoever has firmly accepted this _censorship_ as the chief motive for
the distortion of dreams will not be surprised to learn as the result of
dream interpretation that most of the dreams of adults are traced by
analysis to erotic desires. This assertion is not drawn from dreams
obviously of a sexual nature, which are known to all dreamers from their
own experience, and are the only ones usually described as "sexual
dreams." These dreams are ever sufficiently mysterious by reason of the
choice of persons who are made the objects of sex, the removal of all
the barriers which cry halt to the dreamer's sexual needs in his waking
state, the many strange reminders as to details of what are called
perversions. But analysis discovers that, in many other dreams in whose
manifest content nothing erotic can be found, the work of interpretation
shows them up as, in reality, realization of sexual desires; whilst, on
the other hand, that much of the thought-making when awake, the thoughts
saved us as surplus from the day only, reaches presentation in dreams
with the help of repressed erotic desires.

Towards the explanation of this statement, which is no theoretical
postulate, it must be remembered that no other class of instincts has
required so vast a suppression at the behest of civilization as the
sexua
