Pumping air or water is read as steady effort that keeps something going. Dream books link it to energy you put in — and to drawing up resources from deep down.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
