Cranberry juice is tart and bracing, so dream books read it as a sharp but cleansing truth, and something good that is not entirely sweet.

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.
