Canyon
A deep narrow gorge cut by a river — a long visible record of slow water that did not stop.
A canyon in a dream is the dream's image of a long visible record of slow water that did not stop. The canyon was not cut in a season; the canyon was cut by the river that ran every day for an unimaginable stretch of years. The dream brings the canyon when something in your life — a long working habit, a long resentment, a long love — has cut a feature into the landscape of you that did not exist when the water first started running. A canyon stood at the edge of, the depth taken in honestly, is the dream affirming that the long process is being acknowledged for what it actually made. A canyon ignored as if it were not there, with the dreamer still pretending the ground is flat, is the dream noting that the long cut is part of the geography and is not going to be talked out of being one.
