A high five stands for shared success and easy camaraderie. Dream books read it as recognition, and the pleasure of a win that is not yours alone.

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.
