The car is a modern dream-symbol for how you move through life. Driving confidently on an open road reflects autonomy and momentum. Sitting in the passenger seat may mean someone else is steering decisions that are rightfully yours.
Brakes that fail speak of a pace you can no longer control; a car that won't start, of stalled motivation or blocked plans; getting lost, of a route chosen by habit rather than desire. A crash is rarely prophecy — more often it dramatizes a collision course you already sense. Check who was at the wheel: that is the question the dream came to ask.
