As an adjunct to dreamwork, Jung developed a technique he called active imagination that allows anyone to consult an oracle within themselves. Active imagination is a process of consciously dialoguing with our unconscious
"for the production of those contents of the unconscious which lie, as it were, immediately below the threshold of consciousness and, when intensified, are the most likely to erupt spontaneously into the conscious mind."
C.J. Jung, The Transcendent Function
Someone who has learned active imagination is thus able to take some degree of control over his or her own growth process.
