Being shut out of a group or a room is traditionally read as a waking wish to belong somewhere that feels closed. Dream books ask less who excluded you than which circle you were hoping to enter.
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.
