The lines of the palm are a natural pattern no one else shares, and dream books read them as individuality and the shape of your own path. Studying them closely is linked to a wish to understand yourself.
Where in your waking life have you met something like this lately?
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.
