A tablet is read as information and connection held in your hands. Tradition links it to curiosity and creativity, or to a habit of looking at a screen instead of the world around you.
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.
