A world turned upside down is read as confusion and the reversal of normal order. Tradition sees it as a moment when old rules no longer apply.
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.
