Pedals stand for progress powered by your own steady effort. Pedalling easily is read as momentum; pedalling hard without moving, as frustration or effort that is not yet finding grip.
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.
