The vardo is the Gypsies’ house-on-wheels.
If you dream of a vardo or wagon approaching you, there are people coming to visit you, or bringing news to you (which could be good or bad).
If the wagon is going away, you will be parted from a loved one.
A stationary or passing wagon means things will stabilize and not change for some time.
If you are riding in the wagon, you are making progress (and again consider the spiritual connotations, with this being a means of transportation).
If you are driving the wagon yourself, you are in charge of your own life and able to make the decisions.
