Carl Jung was one of the founders of modern psych-
ology

he is best known for his writings on dreams and
the unconscious

for Jung, dreams reflected the content and pro-
cesses of the unconscious, and therefore, the
study of dreams was essential to diagnosis and
treatment

of all the dreams examined in Jung's writings, there
is one that is widely considered to be the most sig-
nificant

it is a dream he had early in his career; and his
interpretation of it lead to conflict with his mentor,
Sigmund Freud, and their eventual split

Jung called this dream, "a kind of structural diagram
of the psyche"; and as such, it was instrumental in
the development of his three-tier model of the psyche

briefly, Jung differentiated between these three
components of the psyche:

- ego-consciousness - our normal, waking-hours
awareness

- the personal unconscious - suppressed or
forgotten material that can be brought back to
consciousness

- the collective unconscious - unconscious material
that is innate, inherited and common to all humans;
some have called it, "a reservoir of the experiences
of our species."

in Jung's dream (re-created in the video below),
he explores a house that is unfamiliar, yet he knows
it to be his own

this house represents the psyche; and its various
rooms and floors represent the various aspects of
the psyche;

from the salon (ego-consciousness), to a lower floor
(the personal unconscious), to a still lower Roman
Cellar (the collective unconscious)
