A homecoming dance or celebration is read as returning to where you belonged and seeing how you have changed. Dream books link it to old friendships, school-era hopes and the wish to be welcomed back.
When this appeared in your dream, what were you feeling?
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.
