Shopping and a Big Black Dog

I had a dream last night that I was at the mall shopping with my best friend, her baby boy (toddler), and a couple of her cousins. We would find something to Buy, then we would all chip in money to buy it. Then the cousins wanted to buy a lacey thong, and they wanted to spend a lot more than I was willing to spend on it. When I objected, they made fun of me. I left. My best friend and her little boy followed me. When we were almost to the parking lot, there was this big black dog. The little boy wanted to go pet the dog. When he was really close, the dog barked really really loudly. This made the little boy, and his mom, cry.
