Black Chain in dreams
A strong connection — sometimes wanted, sometimes restraining.
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 Chain
A chain in a dream is the dictionary's image of a strong connection. The reading depends on whether the chain is wanted: a chain on a door is protection; a chain on your wrist is the dictionary's image of a tie you no longer want.
Where you often see it. A chain that links two objects. A chain around a wrist. The dream uses the chain for a strong connection — sometimes wanted, sometimes restraining.
What it is not. A chain is not always restraint. The dictionary reads it as connection in its sturdy form.
Related in the dictionary. Read chain with rope (the softer cousin), ring (the closed circle), and any scene of binding.
