Still trying to figure out what the heck is this

Back in early 2020, I parked my car at irqah square to grab some food (24.6866944, 46.5825000), and when I returned, I noticed this strange handprint on the side of my car. At first, I thought it was just dust, but when I looked closely, it seemed eerie—almost like a skeleton hand or claws.

I posted about this back then but didn’t get any clear answers. I recently found the photo again and decided to share it here. Has anyone seen anything like this or have any ideas about what could’ve caused it?
