Public fountain
A built water source in a square — the town's open supply, available to anyone who comes with a vessel.
A public fountain in a dream is the dream's image of open supply made available to anyone who comes with a vessel. The fountain is not someone's well; the fountain is the agreement of a town that everyone gets to draw from the same source. The dream brings the fountain when something in your life — a shared piece of knowledge, a common kindness, a publicly held resource — is currently being kept open for use. A fountain running clear with people filling jugs is the dream affirming the kept commons. A fountain dry, or fenced off, or filled with rubbish, is the dream noting that the open supply has been withdrawn from the public, and the town is going to have to find its water in places that are not for everyone.
