Disembodied Skull or Optical Illusion?

USPA NEWS - I took this picture on March 17, 2019 shortly before 8:30 PM. I decided to share it with my readers because I think it has great entertainment value.
I was on my property burning some wood last night, and decided to take some pictures. When I transferred the pictures to my computer I noticed that the very first picture that I took of the fire appeared to (very closely) resemble a disembodied human skull, a fact that seemed even more strange when I looked thru the rest of the photos I took of the same fire and didn't notice anything unusual.
I am not offering this article as proof of an afterlife, nor am I definitively claiming it as proof of ghosts or demons. However in my opinion this photograph in my opinion was too interesting to ignore, and so I decided to share it with you.

Thank you to all my readers for taking the time to read this article. I normally prefer to report on current events, and entertainment news, however something in the back of my head kept telling me that I should share this image with my readers because it is not that hard to find images of skulls or faces in flames on the internet, but most (if not all) of them have been altered to look that way, but you know you can trust that my image is 100% real and untouched aside from cropping it so that the "skull" would be clearly seen in the center of the photograph, and I also resized it so I could share it on social media accounts, that is the extent that I edited it to. Even my own nephew John Casey couldn't believe what he was seeing when he saw my Facebook post to which I had shared the image. Considering what it looks like I can't say I blame him for his hesitation.
