The riverbed is the shape that guides the flow, and it stands for the habits and foundations that steer your life. Seeing it clearly is read as noticing what lies beneath the movement.
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.
