A tree hung with ribbons or notes of wishes is read as hope placed outside yourself. Tradition sees it as longing and faith, and as a question about what you truly want.

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.
