The meaning of a dream about a journey will depend upon where you are going and the form of transportation that you use.
Superstition-based dream interpretations say that if you go on a voyage by sea, you will have an unexpected visitor, and that if you take a trip to the shore, you will receive money.
Journeys in dreams almost always figuratively reflect your journey through life.
The journey itself or the destination or departure point can all be significant to interpreting your dream.
You have to ask where were you going in the dream? What were you leaving behind in the dream? What emotions were you feeling on the trip, sadness, happiness, joy, regret?
