To dream that you are applying your brakes signifies that you should slow down in your business and/or personal affairs. You have been living on the fast lane and you need to take it easy. Alternatively, the dream may be a pun on “break”. Perhaps you need to take a break or perhaps you need to break off some relationship.
To dream that your brakes fail or that you can’t reach the brakes forewarns that you lack stability in your life. Now is not the time to take risks. Your life is out of control and you need to make some significant changes. It may also not a bad idea to check out the brakes in your car, as you mind might have picked up subtle cues and is manifesting the problem in your dream.
