Day of 5000 Mysterious "Snowmen"

Photo date: December 4, 2019. Photographer: Mark Mahin.

I took the photos below while photographing only ordinary drops of pure, clean water falling in front of a black featureless background.  On this day I got a massive repetition of two different motifs: a face-like motif and a "snowman" motif.  The "snowman" motif consisted of a smaller circle on top of a larger circle, both on the right side of an orb.  I saw such a "snowman" motif appear more than 5000 times in most of 1600+ consecutive photos, with the "snowman" motif appearing at least several times in most of these photos.  Below are two such photos showing the "snowman" motif:

Below are two such photos showing the "snowman" motif.  The hole on the left appeared in a certain fraction of these photos showing the "snowman" on the right (the two photos were taken before the photos above).

The motif shown here resembles the similar "snowman" motif shown in this post.
