Is there a ghost in this image, or is it just an optical illusion?
The latest photo driving the internet insane is bound to give you nightmares -- or at least a serious case of the heebie-jeebies.
This picture in question, which depicts a group of girls who worked in a linen factory and was taken more than 100 years ago, resurfaced online after a woman named Lynda sent it in to the website Belfast Live.
She told the site: "Great to see an old photo of my Granny, in the by-gone years photo, when she worked at the mill. She was Ellen Donnelly (nee McKillop) and she is fourth on the right in the second row down. My dad has this photo at home... a family ghost picture!!"
If you haven't seen the ghost yet, check out the fingers resting on Lynda's grandma's shoulder.
Seen it yet? Here it is close up.
It's unclear who the hand belongs to since all the girls seem to have their arms crossed, and there is no one standing on the side of the woman from which the hand seems to be coming from.
"I don't really believe in ghosts," said Lynda, "but there have been a few odd going-ons around this photo, so I hope this doesn't cause any more!"
Could be Photoshop, could be a disgruntled spirit.
Either way, we're sure paranormal deniers and ghost enthusiast alike can agree on one thing here ...
