The underground normally symbolizes the subconscious. Things that are covered, interred, or that emerge from the ground represent qualities that come from the deepest part of your personality. It could be a positive or negative dream. Digging in the ground could be frightening, but sometimes it is useful in order to know secrets and hidden truths that you would otherwise miss. Further, exiting an underground tunnel and reaching the light represents a triumph over adversity. To interpret this dream it is important to pay attention to the sensations that you feel, and to the events that occur therein.
