A blog stands for thoughts made public, a diary with an open door. Writing one in a dream is read as a need to tell your story in your own words.
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.
