Purple Brooch in dreams
A pinned ornament on outer clothing — a small, visible statement about who you are.
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 Brooch
A brooch in a dream is the dream's image of a small, deliberate, visible statement about identity. Unlike a ring or a necklace, a brooch is pinned on the outside of what you are wearing; it announces. The dream brings the brooch when something in your life — an affiliation, a memorial, an opinion — is being worn where other people can see it. A brooch fastened with care is the dream telling you the statement is intentional and owned. A brooch lost from the coat is the dream noting that a small visible part of how you have been signalling yourself has fallen away unnoticed.
