The material which makes up the avalanche is snow, and snow is frozen water. Water symbolizes your emotions, the unconscious, and, at times, life itself. Therefore, this dream is about rapidly and violently descending emotions and thoughts. Emotions which may have been repressed have finally been unlocked and may be overwhelming you. You may have this dream during emotionally turbulent times of your life, or in your dreams you may be remembering and reliving some difficult emotional experiences. Old dream interpretation books say that burial in an avalanche may result in good luck in the near future. Therefore, they think that it is a dream of the contrary.
