Filling in a form is traditionally read as being asked to define yourself in boxes that do not quite fit. Dream books link it to bureaucracy, waiting for approval and the fear of getting a detail wrong.

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.
