Pizza is cut into slices to share, so dreams of it are read as friendship, celebration and how much of something you feel you are getting compared with others.

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.
