Pareidolia (nonfiction)

Satellite photo of a mesa in the Cydonia region of Mars, often called the "Face on Mars" and cited as evidence of extraterrestrial habitation. Subsequent higher-resolution photos from multiple viewpoints demonstrated that the "face" is in fact a natural rock formation.

Pareidolia (/pærɪˈdoʊliə/ parr-i-DOH-lee-ə) is a psychological phenomenon in which the mind responds to a stimulus, usually an image or a sound, by perceiving a familiar pattern where none exists (e.g., in random data).

Common examples are perceived images of animals, faces, or objects in cloud formations, the Man in the Moon, the Moon rabbit, hidden messages within recorded music played in reverse or at higher- or lower-than-normal speeds, and hearing indistinct voices in random noise such as that produced by air conditioners or fans.
