Blurry Shapes in a Campfire Photo

I was asked to take a look at this photo, particularly at two semitransparent shapes, the very large yellow shoosh on the right, and a greenish shape that resembles the top half of a person viewed from the side.

Relevant Exif data:
Code:
Manufacturer: Apple
Model: iPhone X
Software: 13.3.1
Date and Time: 2020:07:24 22:46:12
Exposure Time: 1/4 s
FNumber: F1.8
Exposure Program: Auto
ISO Speed Ratings: 400
Date and Time (original): 2020:07:24 22:46:12
Brightness: -2.1593
Exposure Bias: 0 EV
Metering Mode: Multi-segment
Flash: Yes, auto
Focal Length: 4.0 mm
So a typical night exposure with an iPhone X with flash. You can verify the the flash firing as it illuminates the retroreflective stripes on the chairs on the right, and the dog's eyes.

The "humanoid" figure seems to be the thing that captures most attention. On an iPhone screen it must have looked rather like a human, facing left, with eyes, a flat nose and a mouth.

But looking closer, and improving the contrast, you can see all of the profile is actually from the back of the chair:

If we remove the chair detail, we are just left with some green blobs:

One might be tempted to view the lighter area on the right as hair, but it's just the yellow streak overlaying these green blobs.

Both artifacts seem to be something close to the camera. The yellow streak reminds me of a hair. Here's a hair close to the camera (iPhone X) illuminated by the flash.

You can see similar longitudinal streaks, and the circle at the end.

But in my photo the background is dark. If a hair is fully illuminated by the flash then it become opaque:

So possible it's something that's a small moving speck, like some falling ash, or a tiny flying insect.

The green blobs could possibly be a bit of foliage, but again it's hard to replicate.

I'd investigate more, but as you can see, I'm still moving house. Any suggestions?
