Being uninvited, or arriving where you were not asked, is read as fear of exclusion. Dream books link it to wanting to belong, or to pushing into a space you sense you are not welcome in.
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.
