An ancient predator long gone, the sabre-toothed cat is read as an old fear that still feels huge. Dream books link it to primal threat, or to power from a past that has ended.
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.
