In general, dreams about blue color often symbolize peace and tranquility. A positive color related to development of a person’s intellect and emotional state. Dark blue can also suggest mature personal insights into life, or if the color is attached to a negative symbol it might point towards a depressive state, negative thoughts or intuitions, and being gloomy. This is why dreamers notice blue waters that connect them to their unconscious emotional state.
