A grid lays order over open space, and dream books read it as planning, measurement and control. Feeling caught in one suggests life mapped out too tightly; drawing one, a wish for structure.
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.
