An offering placed on an altar is read as gratitude or a request given form. Dream books link it to what you are willing to give up in exchange for peace, help or connection.
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.
