A pen pal is read as connection through words and distance. Tradition sees it as friendship built slowly, or a part of you that opens up more easily in writing.
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.
