Asbestos was once prized and is now feared, so it is read as hidden danger in something you live alongside. Dream books take it as a worry about what lies inside old structures, habits or relationships — a symbol, not a warning about health.
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.
