Dead phone
A phone with no battery — a connection device that has run out of the power it depends on.
A dead phone in a dream is the dream's image of a connection device that has run out of the power it depends on. The phone is intact; the energy is gone. The dream brings the dead phone when something in your life — a relationship maintained by messages, a network of contacts, a means of reaching for help — has lost its charge and is no longer available when needed. A phone plugged in and recovering is the dream affirming that the supply can be restored. A phone dead at the moment the call needed to go out is the dream noting that the maintenance of the connection was deferred too long, and the specific emergency now finds the line down.
