This word has to do with human figment of imagination. It could be synonymous with the words of daydreaming. There are tow aspects when a mirage becomes a reality for human expectation to reflect a human desire. However the two aspects are not felt or touched. The first is constantly appearing in dreams. While the second is also appearing in the hot summer isolated from everything. While a person is dreaming about water to drink and this is not realistic. Thus a mirage is false.
