A scraper removes old paint, ice or residue, read as clearing away what has built up. Dream books see it as preparing a clean surface for a new start.
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.
