It symbolizes intimately desired things. If we want to get some dollars it symbolizes the desire for another person of the opposite sex. To find dollars and be afraid of being seen taking them refers to illicit relations. To buy something and be given more dollars or find dollars means that what we bought had a value higher than we imagined, in the moral, material, or sentimental sense. If our lover steals from us it means we exaggerate our love sacrificing things that are also important. To lose money indicates we fear losing something very dear.
