The bowl is an open, receiving shape, so dream books link it to receptiveness, nourishment and what you are willing to hold. An empty bowl is traditionally read as a need waiting to be filled.
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.
