Quiet mouse
A mouse moving without sound in the house — small, unwelcomed presence that lives off what is dropped.
A quiet mouse in a dream is the dream's image of a small, unwelcomed presence that lives off what the household drops. The mouse is not malicious; the mouse is taking advantage of carelessness. The dream brings the mouse when something in your life — a small habit, a minor cost, a quietly running process — has set up in the corners of a household that does not realise it is feeding it. A mouse noticed and the food sealed is the dream telling you the supply line has been cut. A mouse multiplying in a pantry left open is the dream noting that the small presence has become a population, and the carelessness has produced a bigger problem than it intended to.
