A haircut is read as change, a fresh start or cutting something out of your life — an old habit, a tie, a version of yourself. Cutting your own hair is usually taken as a deliberate decision to change, while someone else cutting it points to change that others are steering. A bad or uneven haircut suggests worry about a choice already made, or about how others now see you. Having your hair cut very short is read as a wish to be lighter and freer. It can help to notice what you have recently wanted to trim away.

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.
