A corset is read as shaping and restriction at once — beauty bought with breath. Dream books link it to expectations that hold you in, and to the relief of loosening them.

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.
