Dreaming of a specific body of water such as a lake must be analyzed according to its setting and the entire contents of the dream and much like dreaming of water in general, the clearness of the lake also has to do with the omen or situation it refers to. Clear water being the best. To dream of being in a boat on a calm, serene lake shows that you have much peace and happiness coming your way. If the lake is storm tossed then your life will take a turn for an emotional upheaval and possible losses. Seeing a lake in a glen with sunshine sparkling on the surface portends great good luck in all your endeavors.
