 Pareidolia ( /pærɨˈdoʊliə/ parr-i-doh-lee-ə) is a psychological
phenomenon involving a vague and random stimulus (often an image or
sound) being perceived as significant. Common examples include seeing
images of animals or faces in clouds, the man in the moon or the Moon
rabbit, and hearing hidden messages on records played in reverse. The
word comes from the Greek para- – "beside", "with", or
"alongside"—meaning, in this context, something faulty or wrong (as in
paraphasia, disordered speech) and eidōlon – "image"; the diminutive
of eidos – "image", "form", "shape". Pareidolia is a type of
apophenia.
