Following a tour guide is read as letting someone else lead you through unfamiliar ground. Tradition sees it as a wish for direction, or a question of whose route you are really taking.

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.
