Wind chime
Tubes hung to sound in the wind — the house's small voice given to invisible movement.
A wind chime in a dream is the dream's image of an invisible movement made audible. The wind chime does not produce; it converts. Air the room could not see becomes a sound the room can hear. The dream brings the chime when something in your life — a mood, a presence, a shift in another person — is moving through your space without being announced, and a small part of you has begun to register the passage. A chime sounding gently in clear air is the dream telling you that the listening is in place and the small signals are being received. A chime ringing violently in a closed room with no open window is the dream noting that something is moving through your house that cannot be sourced to ordinary weather.
