Training wheels are read as support while learning something new. Dream books link them to beginnings and dependence, and to the moment when it is time to try balancing on your own.
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.
