In the world of dreams the rules of reality do not necessarily apply. Each dream is unique and it's a direct link to the soul and spirit. Psychology provides its own theories on what dreams mean, but so did tradition and the study of dreams for thousands of years before any relevant science had developed.
Dream Meanings - Moon
The moon is associated with love. To see the moon with a few white clouds means that you will have beautiful moments with your loved one. If the moon is covered in thick dark clouds then you will argue with your partner. A full moon means everything will go well in your relationship while a waning moon forewarns of problems and tiffs.
