A toy box is read as a chest of memories from early years. What you find inside — forgotten, broken or dear — reflects how you relate to your own childhood.
Has this come up in your dreams before? What was going on in your life then?
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.
