russian money

I had another dream the other night involving foreign currency. I wonder what that's supposed to mean. All I can remember is that someone I had gone to school with owed me and my husband money for something. It was one of those situations where no specific sum had been settled on. He just kept peeling off more and more Russian bills. I didn't know exactly how much they were worth, but I was pretty sure that he was paying us way more than he needed to. I was a little stressed because I was trying to calculate unknown values in my head as he was handing me money.
