A city skyline is read as ambition and the shape of goals seen from afar. Watching it can stand for hope, or for distance from the life you want.
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.
