When you dream of an accelerator, it signifies the achievement you will have, through your endeavor. This dream could also tell you to move on things a little bit slower, as there is no need to rush, you will reach the task you wanted to achieve for a long time. If you see the accelerator broken or fractured it means that you do not have control in some parts of your life, what you have to do is, to pull yourself together and take that control into your hands to get the results you wanted to get. Do not rush when you will make the important decisions.
