A rain dance stands for calling for what you need — the wish to bring change through ritual and hope. Dream books read it as longing for relief and trust in shared effort.
Where in your waking life have you met something like this lately?
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.
