According to astrological theory, people born under the earth signs of Taurus, Capricorn and Virgo are thought to have predominantly ‘earthy’ characteristics, such as emotional solidity, materialism, practicality and patience. Jungian analysts regard the earth as a symbol for sensation. In dreams, earth often represents the things you take for granted—yet rely on—in life, such as your body, the processes of life, and your family or cultural background. Earth also represents the past, the fallen leaves of your experience from which soil, new structures of self, are built.
Dreams associated with the earth, therefore, such as lying on the ground, may show that you need to be more grounded, practical and realistic in waking life. You may need to concentrate on worldly matters rather than flights of fantasy. To dream of the planet earth may be a symbol of your true self.
If you were gardening in your dream, creativity is probably indicated; the dream may be referring to your psychological growth and increasing emotional or financial security.
