When the power fails, everything familiar stops at once, and dream books read it as feeling cut off from your energy or support. It also stands for an enforced pause that asks you to slow down.
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.
