s infantile memories and wishes. [Sometimes this is already
recognizable in the manifest dream content. Usually, however, it is first
disclosed by psychoanalysis. Strongly repressed, and therefore difficult
of access, is this infantile sexual material. On the infantile forms of
sexuality, see Freud, "Three Contributions to Sexual Theory."] It reaches
back also from the complicated and completed to a more primitive function,
from abstract thought to perceptual images, from practical activity to
hallucinatory wish fulfillment. [The latter with especial significance in
the convenience dreams. We fall asleep, for instance, when thirsty, then
instead of reaching for the glass of water, we dream of the drink.] The
dreamer thus approaches his own childhood, as he does likewise the
childhood of the human race, by reaching back for the more primitive
perceptual mode of thought. [On the second kind of regression the Zurich
psychiatrist, C. G. Jung, has made extraordinary interesting revelations.
His writings will further occupy our attention later.]

Nietzsche writes ("Menschliches, Allzumenschliches"), "In sleep and in
dreams we pass through the entire curriculum of primitive mankind.... I
mean as even to-day we think in dreams, mankind thought in waking life
through many thousand years; the first cause that struck his spirit in
order to explain anything that needed explanation satisfied him and passed
as truth. In dreams this piece of ancient humanity works on in us, for it
is the germ from which the higher reason developed and in every man still
develops. The dream takes us back into remote conditions of human culture
and puts in our hand the means of understanding it better. The dream
thought is now so easy because, during the enormous duration of the
evolution of mankind we have been so well trained in just this form of
cheap, phantastic explanation by the first agreeable fancy. In that
respect the dream is a means of recovery for the brain, which by day has
to satisfy the strenuous demands of thought required by the higher
culture." (Works, Vol. II, pp. 27 ff.)

If we remember that the explanation of nature and the philosophizing of
unschooled humanity is consummated in the form of myths, we can deduce
from the preceding an analogy between myth making and dreaming. This
analogy is much further developed by psychoanalysis. Freud blazes a path
with the following words: "The research into these concepts of folk
psychology [myt
