A crossword stands for a problem solved word by word, each answer helping the next. Dream books read an unfinished one as a question you are still turning over.
Does the traditional reading fit your dream, or did it mean something else to you?
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.
