The dream of a lake appearing indicates that it wants peace of mind. The surface of the lake represents a state of mind, so gentle and calm means that it is mentally stable. Even if the lake is calm, unlike the calmness of the surface, it also means that explosive emotions or desires are hidden inside, so the interpretation should vary depending on the situation. A lake with a wave of waves indicates that it is in a state of mental disorder. The dream of crossing over a lake in a boat is a psychological dream that shows a state of trying to allay the overflowing anxiety and tension.
