I would he happy to help you in understanding your dreams. Being naked in dreams is showing vulnerability and humility. Since you weren't seen naked in your prior dreams. I believe it is relating to your relationship with your mistress. It was hidden for that many years but the dream is telling you that this relationship is soon going to be revealed to others around you. I believe with her being concerned about her husband is showing her feelings in real life. She may come to a state of being where she may begin to feel concerned with her husband knowing about yours and her relationship. Money in dreams represents favor, what one is putting time and attention towards. So keep in mind your relationship with your mistress may becoming visible to others very soon. If you have anymore questions please feel free to ask.
