It symbolizes things we desire intimately. If we desire to get money it symbolizes desire towards a person of another gender. To find a treasure and fear being seen taking it is a reference to illicit relationships. To buy something and be given more money or find money means that what we bought had a value higher than we imagined, in the moral, material, or sentimental sense. If our lover steals money from us it means we exaggerate our love sacrificing things that are also important. To lose money indicates we fear losing something very dear.
