Riding a unicycle is read as keeping going with very little support, relying on constant small corrections. Dream books link it to an unusual path you are steering alone.
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.
