A traffic jam could express that your life is not going as you would like. You feel blocked. If you dream that you are a traffic director, it shows your desire to impose your own norms on society. On the contrary, you likely believe yourself to be in a role not meant for you, and that others isolate you. In this case, you should confront the problem. If you dream of a big traffic jam, it means that you will resolve your problems through a lot of patience.
