Fast river
A river moving at speed — water in a hurry past the banks that ordinarily contain it.
A fast river in a dream is the dream's image of water in a hurry past the banks that ordinarily contain it. The river is not gentle; the speed is real. The dream brings the fast river when something in your life — a sequence of news, a cascade of decisions, a relationship moving faster than you can think — is moving past you at a rate that does not allow the usual pauses. A fast river crossed at the right place is the dream affirming that the crossing was timed well. A fast river entered without the right footing is the dream noting that the speed of events has lifted you off the bottom, and you are now being carried where the water decides.
