The Element Encyclopedia
by Theresa CheungIf you dream of a pit, you might suffer from anxieties about female sexuality. Jungians see the pit as an image of unconscious urges that need to be explored with care. To dream that you are in a mine signifies that you are getting to the bottom of a particular problem, and may have even reached its core. The journey you are prepared to take to understand yourself better might be symbolized if you find yourself traveling on the tube or the subway; the same is true of any dreams of tunnels, which generally indicate the need to explore your unconscious. Such dreams may also represent the birth canal and therefore the process of birth.
If there is light at the end of the tunnel, you are progressing positively but if something is blocking the tunnel, some past fear or experience is blocking your progress.
