A plate is read as what you are given to deal with — “a lot on your plate”. A full plate traditionally stands for plenty or pressure, an empty one for hunger of some kind, a broken one for an upset routine.
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.
