We used to have a green marble linoleum tile that you could see human skulls in the pattern...................
Not long ago someone posted on FB a photo of the Horseshoe Bend at Page AZ.
I was shocked to see from the angle they took the photo that it looked like a strange rock “face” in which two hollow areas looked like eyes, the the cracked surface like a nose, and the edge at the bottom a row of scraggly teeth.
The human mind is always seeing something “strange” in the normal.
