A crumpled sheet stands for a draft rejected — an idea or plan you were not happy with. Dream books read smoothing it out again as giving a discarded thought one more chance.
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.
