Milky Way
The dense band of stars across the night sky — the visible edge of the galaxy that contains you.
The Milky Way in a dream is the dream's image of the visible edge of the much larger structure that contains you. On a clear night, in a dark place, the band of the galaxy is unmistakable; the dreamer is reminded that they live inside something. The dream brings the Milky Way when something in your life — a history, a tradition, a vast context — has briefly become visible around you. A Milky Way seen and acknowledged is the dream affirming the larger context. A Milky Way drowned out by city light is the dream noting that the larger context is still there and your current habits have made it invisible from where you are standing.
