A padded cell is read as a place where nothing can hurt you, but where you also cannot reach anyone. Tradition links it to isolation, enforced calm and a wish to be safe from your own turmoil.
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.
