A circuit board is a map of tiny pathways all depending on each other. Dream books read it as complex thinking, nervous energy and connections that must line up to work.

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.
