A paper plate is read as informality, convenience and the temporary. Dream books also see it as something meant to be used once, raising questions of what feels disposable.
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.
