Wearing someone else’s clothes is read as trying on another person’s role or point of view. Dream books also link it to feeling you are living by standards that are not your own.
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.
