Grey Locket in dreams
A small worn container — a private memory carried against the body.
How grey changes the reading
Grey colour layers ambiguity onto the symbol. The base meaning is still there, but the dream is saying you do not yet have the colour information — the situation has not declared itself.
The base reading of Locket
A locket in a dream is the dream's image of a private memory carried close. Lockets hold a tiny picture, a lock of hair, a name — something the wearer can touch but no one else may see. The dream brings the locket when there is a person, a moment, or a loss in your life that you are keeping near you and out of sight at the same time. A locket worn under the clothes is the dream affirming the private keeping. A locket opened in front of someone is the dream marking a deliberate showing of the private memory to a particular witness.
