I dreamed that several people were driving at night.

That means you must have seen this fantasy movie. Moreover, the prediction of dreams is still under study, and no one can accurately interpret dreams. What I hate most is to explain the vague scientific basis of dreams and say something about the cerebral cortex. Many fragments of dreams are composed of random fragments of real life, which may not be meaningful, but many details are the most important. Like what does this policeman look like? What may affect your real life is the key thing or person, and what is this door like? What are the scenes over there and here? A * * * how many people? It is unlucky to die like hell, but if you stay away from doors and people, it means that one of your "disasters" has passed, but it will happen sooner or later.
