The traitor is read as broken trust — the fear of being let down, or guilt over a loyalty you have bent yourself. Tradition treats it as a question about where your allegiance really lies.

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.
