Purple Chain in dreams
A strong connection — sometimes wanted, sometimes restraining.
How purple changes the reading
Purple colour places the symbol between hot and cool — a reading that has both calm and intensity at once. The dream often uses purple for symbols that do not fit the usual categories cleanly. Take the reading more seriously than you would otherwise; the colour is asking you to.
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.
