A painted backdrop is read as the setting you have accepted for your life, convincing only from the front. Seeing it fall or tear points to an illusion giving way.
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.
