What is an omen?

An omen is a sign or warning of something that may happen in the future. It is often considered to be a supernatural or divine indication of events that are about to unfold. Omen can take many forms, such as a natural occurrence like a lightning strike or a bird flying in a certain direction, or a more symbolic event like a dream or vision. In many cultures, people believe that interpreting omens can provide insight into the future and help predict important events. The interpretation of an omen often depends on the culture and beliefs of the people who observe it. Some omens are seen as positive, such as a rainbow, while others are viewed as negative, such as a black cat crossing one's path.
