Answer:
Dreaming of death by getting run over by a car does not forecast an actual death. It is a symbol for being overwhelmed by something beyond the dreamer's control. The danger could be work, a school assignment, a problem at home, or just about anything that comes at you without warning and leaves you feeling overwhelmed. Dreams produce literal images in the same way language uses dramatic phrases such as "she bowled me over," "I feel like I've been hit by a truck," and "he just ran right over me." We know the speaker was not actually hit by a truck. Dreams work in the same way.
