Keychain
A ring of keys carried together — the gathered set of places and things you currently have the right to enter.
A keychain in a dream is the dream's image of the collected accesses of a life — the home, the office, the old car, the relative's flat — gathered on a single ring and carried as one object. The dream brings the keychain when it is asking you to look at the full set of doors you are currently authorised to open and the weight of carrying that authority. A heavy keychain with each key known is the dream affirming that the accesses are real and the responsibilities they imply are being kept. A keychain with keys on it you no longer recognise is the dream noting that some of the accesses you carry have outlived their meaning and the ring needs to be lighter.
