Carrying a tray is read as serving others and keeping many things in balance at once. Dream books link a tipping tray to the worry that one small slip could spill everything.
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.
