Burning Man dream, variation #184

I had another of my recurring Burning Man dreams. In this one, we were there with a ragtag bunch of old friends, strangers and family. None of whom seemed to know anything about where they were. We were setting up camp, and it became apparent that members of my family didn't bring any food or water, because they thought they could buy it on the playa. So I found a car and took one of them to a store, which turned out to be huge and rambling. I wandered off in one direction, he in another. Then I lost him in the store.
