To dream of a lock means perplexity, even confusion. If the lock is on a trunk or a door, the dreamer wishes to look beyond the lock so it is necessary to learn what the trunk door represents. If the hunk holds papers, books, or treasures, then anything relative to such a dream would supply the link needed to make the story prophecy. If the door represents a person, is it a man or a woman? Then, is it a stranger or someone close and familiar to the dreamer? The lock is also a symbol of the sexual organism pertaining to woman.
