A mirage is read as a hope or goal that may be an illusion — something longed for that shimmers just out of reach. Tradition takes it as a prompt to tell wishful thinking from what is real.
Has this come up in your dreams before? What was going on in your life then?
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.
