Thunder represents our feelings of fury. It could be that you will have a discussion. It is very possible that your relationships are too stormy. Hearing thunder also foretells the imminent approach of some danger in your life. If the thunder is accompanied by lightening, you could suffer betrayal by a friend. In ancient Greece, it was believed that the cause of storms was the disputes between Zeus and his wife Hera. In Sumerian mythology, the storm was associated with the roar of the bull and rites of fertility. The dream represents your indomitable and powerful psychic strength.
