A medium who speaks for the dead is read as the wish to reach someone gone, or to hear a message from a hidden part of yourself. Dream books see it as a bridge between the known and the unspoken.
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.
