Have you ever had a dream where you were stuck in a vehicle breakdown? This image is symbolic for its consequences after the breakdown. You are interrupted when you have to wait for help, and maybe hitch a different ride to get to your destination. Your timing gets delayed. Other plans are also affected. Your money is diverted to pay for attending to this event.
The image of a breakdown is a metaphor. It can refer to the intangible aspects which are going to have a breakdown. A relationship could be facing trouble and heading for a split.
If the breakdown hints at being related to your job, then you have to take steps to prepare. You can make repairs, or other arrangements, to manage work related problems.
If the breakdown is referring to a personal relationship, then reflect on what you would do to address this concern.
