An "omen" is a phenomenon or event that is believed to predict future occurrences, often interpreted as a sign of good or bad fortune. Omens can take various forms, such as unusual animal behavior, natural events, or specific occurrences that hold cultural significance. Different cultures have their own interpretations of omens, which can influence decisions and beliefs. In many traditions, omens are seen as messages from the divine or the universe, guiding individuals in their choices. For example, in ancient Rome, certain birds were observed to determine the favor of the gods, while in various indigenous cultures, specific animal sightings might signal important changes ahead.
