In the old tale breadcrumbs marked the way back home. Dream books read them as a trail to follow, clues left behind, and a wish to find your way back.

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.
