Wearing hand-me-downs is read as inheriting roles or expectations that were made for someone else. Tradition also sees it as thrift, continuity and finding your own shape in what came before.
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.
