Truck

Trucks like cars are a means of transportation signifying large transitions from one place to another. It suggests you might be carrying a bigger load along than expected to your next destination. To dream of an 18 wheeler or semi truck implies a major change that moves the dreamer from one phase to another.

This can symbolize a ministry for a Christian or a rough and rugged style of living for a non-believer

The truck symbolizes motivation and your desire to move forward. Unlike a car however, driving or seeing a truck can be exploring what you are carrying with you that may need to be released. See Vehicles and Places of Transportation.
