To see a swimming pool full of water in your dream is lucky, symbolizing that you will find much happiness and pleasure in friendship and love. An empty pool means trouble in love and friendship, or that you are not feeling enough affection in your life. A swimming pool is about your spiritual side. These dreams normally focus on specific spiritual abilities which are indicated by other symbols in the dream.
