A prize is read as reward and recognition for effort. Dream books ask what kind of prize it is and how it feels to hold it, since that shows what you truly value.
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.
