Seeing 11:11 on a clock is widely treated as a moment to pause and make a wish. Dream books read it as heightened attention — the sense of a door briefly open between thought and intention.
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.
