A ransom note is read as feeling that something precious is being held hostage — your time, your peace or your choices. Tradition takes it as pressure to pay a price you did not agree to.

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.
