A banknote is traditionally read as value made visible, worth that can be held and given. Crisp notes stand for confidence; torn or worthless ones for doubts about what you have to offer.
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.
