Wall Eye Dolia

By Phil Plait

I love pareidolia, the psychological effect where we see faces in otherwise random or meaningless patterns. You know: Itâs when people see the face of Jesus in wood grain or the Virgin Mary in a reflection. Itâs also when you see birds or dragons or faces in cloudsâany time this happens.

Itâs usually just a fun thing, but sometimes it can be pretty startling. The other day I walked into my bathroom and was freaked out for a moment when I saw the luminous apparition of a woman leering at me:

Seriously, for a split second this got a good reaction from me. The nerve impulses from my eyes triggered the lizard part of my brain, which has way faster reflexes than the higher elitist functions of my cerebrum.

After all, it really looks like a pair of eyes and a mouth with a slightly whimsical cant. The tilt and shape of the eyes struck me as feminine, too. All together, itâs quite a strong pareidolically shaped circumstance.

Once I saw what it really was, I immediately wondered what the source was. The flat mirror you can see on the table in the picture was clearly involved in this, but what were the light sources? The lights over my sink were on, but a quick experiment in eclipsing them didnât affect the saucy womanâs expression one bit. Then the scientist part of my brain kicked in: I looked at the angles, did a little back tracking, and it became clear that the culprits were the recessed can lights in the bathroom ceiling.

I held the camera near the mirror, pointed toward them, to take that shot. As you can see, the arrangement is the same, and again a quick experiment blocking them showed clearly they were the source of this photonic face.

My wife and I got a good chuckle out of this, and never ones not to share the science, we called for our daughter to come see. She took one look and laughed, and then exclaimed, âIt looks like the cover of The Great Gatsby!â She had just read the book, and I have to admit, sheâs right.

I donât think there is any great and profound insight to be had from this resemblance; itâs just coincidence. Perhaps people more prone to faith are more likely to glean messages from these circumstances. I strongly suspect thatâs why pareidolia so commonly leads to witnessing religious icons.

But I canât know this for sure. As Gatsby himself said, after all, âReserving judgments is a matter of infinite hope.â
