A stock exchange is a picture of value rising and falling by the minute. In dreams it is read as worry about worth and risk — your own as much as money’s — and not as advice of any kind.

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.
