A hairbrush is read as self-care and the image you show the world. Dream books link brushing slowly to calm, and pulling at knots to frustration with tangled matters.

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.
