This general interpretation is reinforced by the well-known expression ’to reach for the stars’—or to strive to achieve your ambition—and if your dream focused on one particular star or plant, your dreaming mind may have been attempting to bring your aspirations to your attention. The sun, the moon and the stars are traditionally thought to influence a person’s destiny and, according to Western astrology, the Zodiac sign under which you were born, derived from the position of the stars and planets at the time of your birth, is thought to influence your character and the direction of your life.
Jung associated different archetypes with specific planets and believed that birth charts would generate archetypal images telling him something about the subject of the chart. He frequently looked at the birth charts of his patients with the assumption that the symbols in the charts made suggestions to him from the collective unconscious about that person’s psyche. Whether you believe in the principles of astrology or not, your unconscious may have tapped into these ancient associations, which is why it is always worth considering them when interpreting your dreams.
