A smart lock is read as security that depends on codes and devices rather than a simple key. Dream books link it to questions of access — who is allowed in — and to unease when the system will not open.
When this appeared in your dream, what were you feeling?
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.
