Playing in the Supermarket

In this dream I was with a lot of people at the the supermarket, and we start of divide times. In this place there were a lot of guns (toys), and we played of war, with base A and B, we catched pistols, bombs, grenades, a lot more guns. I've been hiding myself, when a guy of the other base appear I "killed", it was very funny this dream.
DETAIL: I had this dream when I was very young...
