Mirage

/mɪˈrɑːʒ/noun
ELI5 Mode🧒

A mirage is an optical illusion caused by the refraction of light through varying layers of air at different temperatures, often making distant objects appear displaced or inverted, as commonly seen in deserts. In modern usage, it extends metaphorically to describe unattainable goals or false perceptions in fields like business and psychology, where something seems real but ultimately vanishes upon closer inspection.
