A small room set aside for prayer is read as a quiet corner of the self kept free from noise. Dream books see it as the wish to make space for stillness inside an ordinary day.
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.
