A landslide stands for things giving way all at once after a long build-up of strain. Dream books read it as a loss of footing and as the sense that a situation has slipped out of hand. Watching a hillside collapse is usually read as noticing that something you relied on is no longer stable. Being carried along with the earth is linked to feeling swept into changes you did not choose, while standing at the edge as the ground falls away speaks of a decision point. Tradition also sees a landslide as the land finding a new balance. It can help to notice what feels unsteady beneath you lately.
Does the traditional reading fit your dream, or did it mean something else to you?
