Ans: The worry and anxiety felt during the dream can help identify a break-in dream from a nightmare. A "nightmare" is a frightening and upsetting dream that frequently leaves the person with fear, worry, and helplessness. Even though it isn't always as bad or painful as a nightmare, having a dream about a break-in can make you feel vulnerable and anxious. In addition, compared to a dream about a break-in, nightmares frequently have a worse or more upsetting result.
