A boutique is read as individual style and the wish to stand out. Dream books take it as refining your image, and as a question about what truly suits you.
When this appeared in your dream, what were you feeling?
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.
