A kidnapper is read as something that takes control away suddenly: a pressure, a habit or a person who leaves no choice. Tradition treats the dream as anxiety about losing your own direction, not as a warning of real danger.
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.
