A cash machine is read as access to your own resources, in energy as much as money. One that refuses your card speaks of feeling blocked from what you have earned.
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.
