The meaning of a dream involving a car depends very much on its details. If the car was merely a means of transport, it has, in itself, no particular significance, and other details of the dream should be carefully considered. However, if the car was speeding, you could expect some sudden news from a distance; an accident forecasts the recovery of something that was lost. If the engine lost power or stalled, or if you ran out of gas, you could be embarrassed by misplacing your confidence and/or affections.
