The sand in the desert gets heated to very high temperature during daytime. The layer of air in contact with it also gets heated. The layer above it is slightly cooler and so on. As we go higher, the air cools rapidly and the density and refractive index increases. This makes the light ray coming from the sun to bend and distort as it passes through the different layer. Total internal reflection takes place. People imagine that they have ‘seen’ an oasis or town on the horizon. Sometimes the blue sky is reflected from the land surface and there appears to be a lake or a sheet of water.
