If the deep, precipitous sides of a chasm or large hole threaten to engulf and swallow you up in a dream, or if an abyss suddenly opens up in front of you, transforming a previously pleasant scene into a terrifying one, could your unconscious have been warning you that your position in waking life is not as stable as you might think and that you could be facing unexpected mishaps or pitfalls? Chasms and holes in dreams always suggest an element of the unknown or something in some way risky, and they urge the dreamer to make a decision one way or another in waking life. Perhaps you dreamed of teetering on the brink of a ravine, petrified that you would lose your footing? Such a dream may be warning you that you are in danger of falling into an emotional black hole, out of which you feel powerless to emerge. Also, because the earth is a symbol of the archetypal mother, devouring chasms may represent a devouring maternal figure in your life, intent on dominating you or dragging you under.
