A gender reveal is read as the moment a vague future takes on a clearer form. Dream books link it to anticipation, surprise and other people gathering around your news.
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.
