If you dream of your country's flag, it signals victory in times of conflict and flourishing prosperity during peacetime. For a woman, dreaming of a flag may suggest she will find herself drawn into a romantic entanglement with a military man. Foreign flags in a dream point to broken trust and fractured relationships — between nations or between friends. If someone signals you with a flag, take it as a warning to guard both your reputation and your health, as both may be under threat.
