The mantelpiece is where a home displays what it treasures, read as the memories and achievements you put on show. What stands there in the dream points to what you most want seen.

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.
