Handing your keys to a valet is read as trusting someone with what moves you. Dream books also link the figure to service, status and convenience.

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.
