Driving without a license stands for doing something you feel unqualified for or unauthorised to do. Dream books read it as impostor feelings, or as stepping into a role before you feel ready.
When this appeared in your dream, what were you feeling?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
