The smell of rain on dry earth stands for relief after a long wait and for memory stirred by scent. Dream books link it to renewal and to the comfort of something familiar returning.
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.
