To dream of a lock, denotes bewilderment. If the lock works at your command, or efforts, you will discover that some person is working you injury. If you are in love, you will find means to aid you in overcoming a rival; you will also make a prosperous journey.

If the lock resists your efforts, you will be derided and scorned in love and perilous voyages will bring to you no benefit.

To put a lock upon your fiance'e's neck and arm, foretells that you are distrustful of her fidelity, but future episodes will disabuse your mind of doubt.
