Omens are signs or events that are believed to predict future occurrences, often interpreted as warnings or messages. They can be natural phenomena, such as unusual weather patterns, or specific actions, like the behavior of animals. Different cultures have their own interpretations of omens, which can vary widely in meaning and significance. Historically, omens have played a role in various belief systems, including ancient Rome and Mesopotamia. People often look for omens in dreams, astrology, or even everyday occurrences. While some view them as superstitions, others take them seriously, believing they can influence decisions and actions.
