To see a swimming pool full of water in your dream is lucky, symbolizing that you will find much happiness and pleasure in friendship, love and marriage.
An empty pool means trouble in love and friendship, or that you are not feeling enough affection in your life.
If the pool contained muddy or dirty water, you are wallowing in your negative emotions. You need to devote some time to clarify your mind and find inner peace.
This dream may also suggest that your thinking and/or judgment is unclear and clouded.
