A burning car is read as intense emotion consuming what carries you forward. Tradition links it to anger, passion or stress that has grown too hot, and to a transformation of a way of life.
Has this come up in your dreams before? What was going on in your life then?
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.
