Underground river
A river running through caves below the surface — water that does its work where no one can see it.
An underground river in a dream is the dream's image of water that does its work where no one can see it. The surface looks still; somewhere below, the river is carving, carrying, and shaping. The dream brings the underground river when something in your life — a deep emotional process, an unspoken family current, a long inner change — is moving with full force below a surface that does not show it. An underground river acknowledged and listened to at the surface vents is the dream affirming the honest awareness of the hidden current. An underground river ignored until it has cut a cave the house is now sitting over is the dream noting that the hidden current was real and was not consulted, and the surface above it is now structurally compromised.
