Being locked out of your car is read as being shut out from your own plans. Dream books link it to frustration, a missing key to progress, or a small oversight blocking a big step.
Where in your waking life have you met something like this lately?
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.
