So.... Quite creepy. The "shape" certainly resembles a hunched, deformed figure. But what are we actually seeing here? Here's an excellent breakdown of the "demon's" constituent parts from a metebunk user.
Now I don't know about you, but once I viewed that breakdown I could no longer "see" the demon or alien in the original image. That's the power of pareidolia and a great example of why we should never just believe our eyes when it comes to assessing indistinct images of alleged paranormal entities.
