A crop top is read as playful boldness and comfort with the body. Dream books link it to youthfulness, self-expression, or a question of how much of yourself to reveal.

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.
