The term 'Of Things To Come Sign' refers to an OMEN, which is a sign or warning of a future event. An OMEN can be either good or bad, and is often seen as a portent of things to come. In many cultures, omens are believed to be messages from the gods or other supernatural forces, and are taken very seriously. Omens can take many forms, such as a strange noise, a sudden change in the weather, or a particular animal appearing in an unexpected place.
