Et fata morgana er reelt nok. Det er et optisk fænomen, det er ikke
indbildning. Selvom hjernen fortvivlet forsøger at bringe mening i hvad det
ser.

The fate morgana mirage is one that can occur only where there are
alternating warm and cold layers of air near the ground or water surface.
Instead of traveling straight through these layers, light is bent towards
the colder, hence denser, air. The result can be a rather complicated light
path and a strange image of a distant object. A fate morgana actually is a
superposition of several images of one object. Typically one image is
upright more or less above two inverted images that may be mingled together.
The images may undergo rapid changes as the air layers move slightly up and
down relative to the observer.
