A cartwheel is read as exuberance and childlike joy in the body. Dream books see it as energy released, with a small wish to show off.
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.
