Sometimes I discover huge, beautiful turquois swimming pools in hidden rooms in huge houses but don't go in. Sometimes I discover a glass wall behind which is the ocean. Sometimes I get to dive over and over into a pool from a diving board. Once I rescued my dog from a torrential rain storm. Once the yard of my childhood home flooded in the rain and I joyously swam there.
Water is our emotional life.
Many of your dreams are about helping people swim or save them, so in real life it may be that you are the shoulder that many people cry on, or the one to give a pep talk when friends are down. Discovering hidden turqoise waters, means discovering different parts of yourself that you are letting go idle and that you have greater potential than is being used. Dogs can represent friends, rain a release of emotions and snow a time of cool feelings.
