Phantom hand
Okay, of the photos we’ve seen so far, this may well be the most chilling. What you’re seeing here is an old picture of a group of young ladies gathered around just before high-contrast photography became more popular.

Furthermore, if you look closely, you’ll notice a hand on one of the young ladies’ shoulders on the correct side of the photo. And to make matters worse, it isn’t connected to any of the other young women. This makes us shudder to look at it!
