A raffle is read as waiting to be picked from among many. Dream books take it as hope for recognition, or as the feeling that outcomes in your life are being left to chance.
When this appeared in your dream, what were you feeling?
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.
