A last will is read as the question of legacy: what you pass on, and what you are expected to carry from those before you. Dream books see it as a reckoning with values rather than with property.
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.
