A glowing warning light is read as something asking for attention before it gets worse. Dream books see it as a signal from within that you may be ignoring.
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.
