A cutting board is where things are divided and prepared, so it is read as planning, breaking a task down and getting ready. Folk tradition also links it to decisions about what to cut out.
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.
