Drumming is read as rhythm, heartbeat and a call to gather. Dream books take a steady beat as inner pace found, and a frantic one as pressure building.
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.
