Pegs hold washing out in the open air, read as private matters hung up where others can see. Dream books also link the clothesline to patience and simple domestic order.
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.
