Black Collarbone in dreams
The bone at the base of the neck — a slender, exposed structure that holds the shoulder out from the body.
How black changes the reading
Black colour pulls the symbol toward the not-yet-known — depth, hiddenness, the part of the situation that has not yet come into the light. The dream is rarely warning you; it is showing you that there is more to the picture than the part you have been looking at.
The base reading of Collarbone
A collarbone in a dream is the dream's image of a slender, visible structure that does important load-bearing work — it holds the shoulder out from the body, and it is one of the first bones to break when something heavy lands on the shoulder. The dream brings the collarbone when a quiet, visible part of you is currently doing more structural work than it appears to. An intact collarbone is the dream telling you the load is being held. A broken collarbone is the dream marking that the slender structure that was supporting the larger frame has finally given way.
