Zip or zipper dreams are usually connected with something being open or closed, as are zippers in real life, which can also be broken.
Sometimes zipping something up is connected with keeping something secret or out of sight.
Zippers are mostly connected with clothing, in jeans and jackets, and are usually closed to keep us warm or opened to cool us down or when we go to the bathroom – especially in the case of men.
Having your zipper or flies open/undone is a common form of minor embarrassment to men, often because it’s usually pointed out by someone else. This situation in dreams can suggest you’re worrying about your dignity, or how your dignity is viewed by other people.
Dreams where zippers are left open accidentally in jackets and other clothing can reflect a feeling of being slightly exposed, that people are seeing a part of you that you’d rather stay hidden. These feelings could be greater and suggest you feel the situation is out of your control if the zipper is broken and you are unable to close it.
Zippers being open or closed can be indicators of being emotionally open or closed to your friends or family.
