Supernatural signs, such as OMENS, are believed to be a sign or warning of future events. OMENS are often seen as a portent of bad luck or misfortune, but can also be interpreted as a sign of good luck. OMENS can take many forms, from natural phenomena like thunder and lightning, to more subtle signs like a sudden chill in the air or a feeling of unease. In some cultures, OMENS are even believed to be messages from the gods or spirits.
