Trying to drive from the back seat is read as attempting to control your life from a distance. Tradition links it to feeling you are not truly in charge of the direction.
Has this come up in your dreams before? What was going on in your life then?
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.
