What does it mean to dream that my mother-in-law was hit by a car?

A car accident in a nightmare shows that you must re-examine your life: think carefully, is your life out of control, or is it too extreme in dealing with certain things? If you can make a careful plan in advance, take it easy and not be eager for quick success, then you will succeed. If you dream of an accident at home, you are worried about your family.
