Dream about being in a car with no brakes expresses your lacking awareness of something in your life. There may also be a situation in your life that has left you speechless. You are forcing your own ideas and beliefs on others. This is a warning for the past and things that you have put behind you or have forgotten. There is a topic or issue that you want to discuss, but do not know how to bring it up.
Being in a car with no brakes dream symbolises monotony and endless repetition. You are lacking some emotional, intellectual, or physical component in order to feel whole again. You are feeling low and sad. The dream points at your pissy attitude. The same old problems are coming back to haunt you because they were not properly addressed or dealt with in the first place.
If you dreamt about being in a car with no brakes:
There is no need to get upset or uptight about anything. Do your best to relax. The more calm and relaxed you are, the calmer the people around you will be. This kind of environment fosters growth and overall good relations in the workplace.
