Dreaming of breaking something means you are reacting poorly to stress or you need a pivot in life. When stressed at a job or relationship, try taking a more stable approach rather than a curt reaction that could potentially do more damage and breaking all the progress made.
You may be at a breaking point in life, and need a pivot in pursuing something completely opposite. If you suffer from health issues, then take a pivot and throw out all the junk food in the kitchen cabinets. If you have trouble waking up early, then keep all electronics outside the bedroom.
