DEMOLITION

A dream where something is demolished can suggest that some kind of change is taking place in your waking life. Alternatively, the dream can imply that you have built up emotions, are being self-destructive,  or you are facing some kind of distress or disturbance in some area of your life.

To see someone else carrying out the demolition can suggest you are being passive or feeling powerless in some situation involving change. If you are demolishing something in the dream then it can imply that you are looking for more control in some part of your life.
