Machinery is read as routine and the systems that keep life running. Smooth machines point to things working; a breakdown or grinding gears to a part of life that has become mechanical or strained.
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.
