It's just like it sounds. In Cleveland in the 1930s, an unidentified killer murdered 12 men and women. Often, the cause of death was decapitation, followed by dismemberment. The Cleveland Torso Murderer was never caught.

The Overtoun Bridge is located in West Dunbartonshire in Scotland. Many dogs have leapt off this bridge to their deaths, usually from the same side of the bridge. In 1994, a man threw his infant son over bridge, believing he was an incarnation of the devil. Don't cross this bridge.

In 1955, seven people at a rural farmhouse in Hopkinsville, Kentucky, claimed to have been harassed and terrorized by "creatures similar to gremlins." If aliens exist, they are scary assholes.

The Grey Goo is a hypothetical situation that would spell the end of humanity as we know it. Self-replicating robots would build more and more of themselves, consuming all of Earth in the process. So, like, no one build a replicator and we can avoid this shit, OK?

The sheer number of people who have never been heard from again is overwhelming. This list has enough creep factor to make you never want to leave your room again.

13. Rat Torture

Torture is awful in general, but it's even worse when it involves something that can chew on you. During the National Reorganization Process in Argentina, rats were allegedly inserted into the rectum or vagina using a tube. And during the Dutch Revolt, bowls of rats would be placed upside down on prisoners' bodies and heated, so the rats would chew through people's flesh in an attempt to escape the heat.

14. The Voynich Manuscript

The Voynich Manuscript is written using an unknown system and has been carbon-dated to the early 15th century. Cryptographers have tried, but no one has been able to decode this mysterious manuscript.

15. Kaz II


The Kaz II is often referred to as "the ghost yacht." Its three-man crew disappeared, but the ship was found in working condition with its engine on and a laptop running.

16. Cicada 3301

Cicada 3301 is an organization that sets up very complicated puzzles in order to "recruit highly intelligent individuals." People have claimed to have "won" some of the three rounds of recruitment, but no one has come forth to give detailed information on what exactly this organization is doing. Do they have some sinister plot to create some super-intelligent army? Will they destroy us? Who knows.

17. List of Unexplained Sounds

Now that they've figured out that Bloop and Julia are the sounds of icebergs, you can settle into the unknown of Upsweep and The Whistle. They have yet to be identified, because the ocean is a vast den of terrifying, unknown shit.

18. Post-mortem Photography

This page will remind you that there was a time when we posed the dead as if they were living so we could remember them as they were. But instead, we got terrifying dead eyes staring back at us. Nightmares for days.

19. Phantom Time Hypothesis

The Phantom Time Hypothesis alleges that the period of time between 614 and 911 A.D. was added in retroactively, and that events that happened during this time occurred at different points in history, or didn't happen at all. It might just be an unfounded conspiracy theory, but also what if the past and time is all a lie?!
