Dream of hidden Money behind Wallpaper at the bank

"I was cleaning my bedroom when a few bills slipped out from behind the wallpaper. I pulled at it and found more underneath, folded up and tucked into the wall like someone had been hiding money there for years. I kept peeling the wallpaper back, telling myself I would stop after one more section. There were coins, envelopes, and a whole stack of cash that looked new even though some of the bills had old dates on them. My brother walked in and asked where I got it. I told him I had found it, which felt different from stealing, although I knew it probably wasn't mine. He said I needed to hide it before someone came home. Then the room changed into a bank. I was standing in line with a laundry basket full of money. Everyone else was holding normal wallets and purses, so I felt embarrassed. The teller counted everything and said I was short by three dollars. I searched through the basket and found a handful of buttons instead. I started crying because I had been so sure I was rich. When I looked down again, the money was back, but it was blowing around the bank like leaves. I woke up trying to remember where I had put it."
