A flowerpot holds growth within limits, and dream books read it as the space you have to develop in. A cracked or too-small pot points to feeling cramped or ready to be replanted.
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.
