To see or carry a license in a dream represents the freedom or privilege to do something whenever you want. You may permission to pursue or proceed with a new endeavor in your life. It may also reflect more freedom or more access than other people in some way. You’ve been given the “go ahead.”
Negatively, may reflect a total lack of restriction or conscience to do as you please. Feeling that you have a “license” to abuse something.
To dream of driving without may reflect abuse of resources or privileges that you haven’t earned. Using the status of parents, better connected people, or rich friends without permission for your own needs.
Example: Paris Hilton, in her youth, often had recurring dreams of driving her parents car without a license and fearing getting caught. The dreams may have reflected her awareness of herself talking about herself or making decisions on her own that she knew her parents would reject if they ever found out about it. Possibly also a reflection of her awareness of herself being a spoiled rich kid who was showing off with her parents wealth without their knowledge.
