Getting dressed is read as preparing to face the world and choosing a role. Dream books take what you put on as how you want to be seen.
Where in your waking life have you met something like this lately?
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.
