Astonishing Repetitions

On her Facebook page,  Andrea Corsick has an astonishing photo showing an effect like something I've seen repeatedly. The photo (which will probably require a Facebook login) can be seen here.

What we see in her photo is a strange purple-green veil-like object which has four repetitions of a kind of clover-leaf pattern.   I get something similar repeatedly when I photograph falling water drops: a single strange effect repeated multiple times in the same photo, in a way that seems fantastically unlikely to be occurring by chance.   The effect may be face-like details (as shown in these 347 photos), or ring shapes (as shown in these 60+ photos), or stripes (as shown in these 61 photos).  In all of these the same weird thing will show up from 2 to 20 or more times in the same photo. 

Here is an example from March 8, 2018. I took the photo while photographing nothing but ordinary water drops falling.
