Have you ever taken a photo and seen a mysterious shadow lurking in the corner? People say that eyes can play tricks on us, but what about the times there's visual proof of those tricks? "Photoshop exists," you might say. But did it really exist in 1992, when Carlos Diaz took a photo of a possible UFO in Tepoztlán, Mexico?
Some folks might say that it's still a hoax. Others, however, are inclined to believe that there are just some things in this world that we can't logically explain, and that's okay. Folks on Reddit have shared many such photographs. We've gathered the most interesting ones here for you to be creeped out or entertained about!
