Weird camera processing?

Pixel 9 Pro XL here

Please see picture in the link below. I was trying to take a photo of this while minimizing my reflection in the glass. I put on a black hoodie backwards. I'm holding my phone with me left hand inside the sleeve so its not visible. I cover my face with the hoodie hood with my right hand and then put my right arm down before snapping the picture. However my right hand is still there when it shouldn't be. Any ideas? I don't understand what's happening. I googled to try to figure it out and all I could find was "lens flare" but that doesn't seem to explain why my hand is still in the reflection.
