Reunion show

In my dream I was at a girls school or a camp and had been there a while. They were sometimes nasty. On the last day, girls who had left started coming back. And they came back with food items. One girl had a pizza and she was picking off the toppings(one of which was onions) and throwing them at someone who she didn't like. Another girl had chocolate cupcakes or muffins. We were surprised that they were coming back. Some one said "We've never had a reunion show before"
