The strange substance of old séance lore is read as the residue of something unseen made visible. Dream books link it to feelings that leave a trace even after the moment has passed.
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.
