Falling asleep at the wheel stands for not paying attention to something important. Dream books read it as exhaustion, or as a part of life running on without your conscious presence.
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.
