A class reunion is read as measuring your present against your past. Tradition sees it as reflection on how far you have come, and on old roles that still cling.

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.
