Nurul Islam, 37, was enjoying the afternoon with his niece, Mayrian Islam,11, and nephew, Ryhan Kaliq, 9, and snapping pictures in front of a fake Victorian-style ruin when suddenly a "ghost" appeared out of nowhere. At first, Nurul didn't think it could possibly be an apparition. But, then again, he also says he made sure all the other tourists were out of the way before he snapped this shot.

It’s the most wonderful time of the year: Halloween!

New York City actor Joe Cummings made this video capturing what appears to be a homeless woman who secretly lived in his house for an indeterminate amount of time. As recently as July of last year, Joe continued to insist this really happened and is not a prank or joke. There was never another product or release that tried to market itself off this video, so chances are he's telling the truth, which makes it so much creepier. What if there's someone peeing in your sink at home right now? You don't know.
​Galeopterus variegatus, also named Sunda Colugo or the Sunda Flying Lemur, is a nocturnal and arboreal (lives in trees) mammal endemic to Indochina and Sundaland. These animals possess large membranes of skin called patagiums that extend along the limbs, allowing them to glide along distances of up to around 100 meters; given that these animals are only around 40 centimeters in length that's pretty impressive skills! The mottled coloring of these animals also makes them look a bit like the lichen of a tree and therefore helps to camouflage them. 
It’s not important to understand exactly what the "deep web" is, but suffice to say that the majority of what we consider "the internet" is just the surface of a vast network of computers and systems constructed by humans. The owner of the Obscure Horror Corner YouTube channel was reportedly sent this game from one of his subscribers who had found it on a deep web Tor page where users could post random files. This "game" was labeled simply "ZK." After running a Malware check, Jamie the YouTuber started playing the game and recording the results.

“The leaf-tailed geckos are native to Madagascar and are renowned for their camouflage. This individual is just a juvenile. Many of the leaf-tailed gecko species press their bodies against wooden limbs and trunks during the daytime, and their flattened bodies, fringes, and tails eliminate any shadow, making them invisible to predators. At night, they become active and hunt primarily invertebrate prey.” – Mike Martin

The daintily named sea pig is actually a kind of locally abundant sea cucumber that inhabits the world’s abyssal plains up to 3.7 miles beneath the surface. It gets its name from a characteristic pink, eggplant-shaped body and bloated legs that give it a porcine appearance. Like their shallower cucumber cousins, sea pigs play an important role in marine ecosystems. They feed on detritus that falls to the seafloor from the rich waters above, whether plankton or a whale carcass. They walk along on a few large tube feet, using a combination of muscle contractions and body fluids. Modified pairs of legs can act as antennae to detect food.
