A tuber stores energy underground, so tradition reads it as reserves, hidden resources and quiet nourishment. Dream books see it as strength kept out of sight.
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.
