Driving against the traffic stands for going against the current of those around you. Tradition reads it as a sense that your direction clashes with what others expect.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
