Pockets are traditionally read as private reserves — what you keep close and carry with you. Finding something in one points to a resource or memory you had forgotten you held.
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.
