A deckhand does the hard, wet work that keeps the ship afloat. Dream books read the figure as humble effort and finding your footing in a shifting situation.

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.
