The web is overflowing with urban legends of all sorts. These stories usually exist to shock or convince you of something unbelievable, all for the sake of gaining more attention. While platforms like Mytour strive to expose the truth behind these myths, many of us, tired of the absurd, dismiss anything far-fetched the moment we hear it.
But while most of these urban legends are simply false, there are some, the more outlandish ones, that contain more truth than you’d expect. In fact, sometimes the real story is even more unsettling than the myth itself.
10. The True Story Behind the Russian Sleep Experiment That Left Puppies Without Sleep Until They Perished

You’ve probably encountered the infamous urban legend of the so-called “Russian Sleep Experiment,” a tale that was later revealed to be a fictional creation for a creepypasta. The myth describes a scenario where several political prisoners are promised freedom in exchange for participating in a sleep study, where they’re kept awake for weeks using gas, all to observe the impact of sleep deprivation on their behavior. By the end of the study, the participants have gone completely mad, and it's unclear how much of their insanity was caused by the lack of sleep and how much by the gas.
Although these experiments weren’t conducted on humans, a Russian scientist named Maria de Manaceine carried out forced wakefulness studies on live subjects in the 1890s. While it may have been deemed unethical to test this on humans, she chose puppies as the next best alternative. Several dogs were observed over weeks, kept awake through forced activity like handling and walking. They were given adequate food and water, but developed lesions on their brains and perished within a few days. Despite the cruelty, the experiment confirmed that the brain cannot survive prolonged wakefulness—sleep is just as essential as food and water.
9. While Black Cats May Not Be Sacrificed on Halloween, They Are Often Seen as Costume Props

One of the longest-standing urban myths is that black cats, or cats with solid colors, are linked to various types of luck. Black cats, in particular, are often associated with bad luck, and some people even claim that those practicing witchcraft or Satanism use black cats in their rituals—sometimes harming or killing the animals in the process.
The most widespread rumor surrounding this is that people engaging in dark practices adopt black cats around Halloween to sacrifice them during a black mass. However, there is no substantial evidence to support that this occurs on a large scale. This doesn't mean, though, that animal adoption agencies are completely open to letting anyone adopt a black cat during Halloween. Some have made it harder to adopt one during this time, fearing that individuals may just want them as temporary costume accessories without any intention of caring for the animals long-term.
8. Tug-of-War Games Have Resulted in Fingers and Even Entire Arms Being Lost

Tug-of-war is often seen as a quintessential part of picnics and large gatherings, regarded by many as one of the safest and most wholesome games. It’s a team activity that tends to bring people together, leaving everyone laughing as one team pulls the other across the line. However, when proper safety measures are ignored, tug-of-war can be surprisingly dangerous. While playing with just a small group of friends on each side is unlikely to cause harm, the risks grow with larger numbers, and things can quickly go terribly wrong.
As the saying goes, it's all fun and games until someone loses an eye... or a hand. Tug-of-war has a shocking history of injuries, including the loss of hands and fingers—far more than most would ever imagine. In the 1970s, a tug-of-war attempt for a world record in Pennsylvania, involving 2,300 middle school students, ended with the rope snapping and over 200 students injured, including several who lost their thumbs. In 1995, at a Boy Scout event in Germany with 650 participants, over 100 children were injured and two lost their lives when the rope broke. A 1997 competition in Taiwan, involving 1,600 people, resulted in at least 40 injuries, with two participants losing their left arms.
No rope has been designed to withstand the pulling force of thousands of human beings, and when it inevitably snaps, the forces must be redirected somewhere. With so many people pulling, serious injuries and even fatalities become almost inevitable.
7. A Lawyer Jumps Through a Plate Glass Window to Test Its Strength, Ultimately Meeting His Demise

The myth of someone accidentally falling through the window of a skyscraper and plunging to their death has circulated ever since skyscrapers first appeared. While many people consider skyscraper windows to be strong and resilient, they still tend to exercise caution around them, even if the fear is unfounded. However, in 1993, Garry Hoy, a lawyer, decided to test the claim that skyscraper windows couldn’t hold human weight. His bold experiment ended tragically when he jumped through a plate glass window, ultimately falling to his death.
Initially, Garry Hoy demonstrated how ridiculous it was for people to think running into a skyscraper window was a dangerous idea. He performed the stunt several times, convinced that nothing could possibly go wrong. However, one fateful day, he took it too far. While showing off to some law students at the law firm where he worked, Garry ran into the same window twice. We may never know why he chose to try again at the same window, but on the second attempt, the window gave way, sending Garry plummeting to his tragic death.
As far as anyone knew, Garry Hoy was a bright, promising young lawyer with no suicidal tendencies. He simply had an unearned trust in the durability of windows. A building engineer later commented that the windows weren’t built to withstand the force of a 73-kilogram (160 lb) person crashing into them. The engineer expressed surprise that this tragic incident hadn’t occurred during one of Hoy's earlier attempts.
6. Dogs Used as Living Drug Mules, Then Sliced Open Upon Reaching Their Destination

Among the most horrifying smuggling stories are those in which traffickers use extreme measures, including involving their children or pets in their operations. One widely circulated urban legend suggests that a dead baby was stuffed with drugs, and a woman was instructed to pose as the child's mother to get it through customs. Sadly for the smugglers, the plan was thwarted when the woman was caught. However, this story remains unproven, and all accounts come from sources that can rightfully be called ‘fake news.’
While there’s no proof that drugs were ever smuggled inside a dead baby, traffickers have certainly resorted to other horrific tactics. In 2013, authorities in Italy uncovered a vile scheme where smugglers made dogs swallow drugs, then cut the animals open upon reaching their destination to retrieve the contraband. The plot was exposed when a customs agent noticed one of the dogs appeared unwell and ordered an X-ray, which revealed the drugs, bringing the operation to a swift end.
5. A Woman's Eye Became the Unlikely Home for a Bizarre Pile of Contact Lenses Over the Years

We’ve all heard the old tale about leaving a contact lens in your eye for too long, leading to it fusing with the eyeball and becoming permanently stuck. Some versions suggest the lens can never be removed, while others claim it would require extremely painful surgery to free it. However, while it's common for contacts to temporarily become stuck, there is no evidence that they can actually bond with the eye permanently. Most people visit a doctor to address a stuck lens before it turns into a larger issue.
In 2017, a woman from the UK went to see a doctor for cataract surgery, only to have the procedure postponed due to a shocking discovery inside her eye. When the doctors lifted her eyelid, they were astonished to find a blue mass, which turned out to be a cluster of contact lenses stuck together. After further examination, they found even more lenses, bringing the total to 27 that had been trapped in her eye for years.
Apparently, the woman had several instances where she couldn’t locate a contact in her eye, assumed it had fallen out, and simply inserted a new one, without ever consulting a doctor about whether that was the right course of action. While it's reassuring to know that contact lenses won’t permanently fuse with your eye, it's truly shocking to learn that someone could unknowingly live with so many foreign objects trapped under their eyelid without going crazy.
4. People tend to dismiss dangerous ‘challenges’ as nothing more than an urban myth, but the Chubby Bunny challenge has led to fatalities.

Every year, there seems to be yet another reckless ‘challenge’ that teens and kids take on to impress their friends and show off for social media. Some of these are much ado about nothing, harmless antics that create more noise than actual danger, while others are overblown by the media. Take the recent Tide Pod challenge, for instance: though there has been an uptick in poison control calls, there’s no verified death linked to it.
While many of these so-called challenges are exaggerated or even beneficial—like the Ice Bucket Challenge—others may seem innocent but are surprisingly dangerous. The Cinnamon Challenge, for example, has sent many people to the emergency room after they choked. Meanwhile, the Chubby Bunny challenge has been directly linked to multiple deaths. This game involves participants stuffing marshmallows into their mouths and saying ‘chubby bunny,’ but if they spit, cough, or choke, they’re out. Sadly, choking incidents are common, especially among unsupervised children, and Chubby Bunny has claimed several lives. Fortunately, its popularity has declined in recent years as other challenges have come into vogue.
3. While there’s little evidence to suggest that cell phone use causes cancer, landlines might actually be a more significant risk.

The debate over whether cell phones can cause cancer or other brain issues has been ongoing ever since these devices became mainstream. Despite years of research, no conclusive proof has emerged on either side. However, if any risk does exist, it’s probably from long-term exposure to the phone held up to the ear—a practice that’s becoming less common as people increasingly use hands-free devices and speakerphones.
While older generations often warn about the dangers of new technologies, when it comes to telephones, landlines actually pose a more established risk. Though fatalities from landline use are rare, it's crucial to heed the advice of not using a landline during a thunderstorm. If lightning strikes the telephone line while in use, the danger of electrocution is very real, with documented deaths from this exact scenario. Younger users should also be cautious: using a cell phone while plugged into a charger could present a similar risk, especially if the charger lacks a surge protector.
2. Leaning Your Head Out of a Car Window Won't Decapitate You, But It Can Still Be Deadly

We've all stuck our arms, or sometimes even our heads, out of the car window to feel the breeze or let a pet or child do the same. To many, this seems like innocent fun without considering the dangers of how close cars can be to one another or other obstacles. The myth, possibly popularized by concerned mothers, claims that sticking your head or arm out of a car window could result in decapitation or dismemberment.
Fortunately, this is a misconception. Unless you make contact with a sharp object, it's highly unlikely that you’ll lose a body part. However, the danger isn’t nonexistent. There have been cases where people sustained broken arms or tragically died from neck injuries after their head was struck while hanging out of the window.
1. Tight Skinny Jeans Can Impede Blood Flow and Lead to Health Issues

There’s a popular urban legend about a woman who wore her skinny jeans so tightly that she lost the ability to move her legs, eventually needing them amputated and spending the rest of her life in a wheelchair. Although this tale has been shared by many news outlets, it all traces back to a tabloid story without any credible evidence. Despite this, it’s important to note that wearing skinny jeans isn’t without potential risks or drawbacks.
If you’re concerned about the possibility of blood clots or death from wearing skinny jeans, there’s no need to worry. Medical professionals don’t believe the tightness of skinny jeans can cause blood clots. However, they do warn that wearing them too tightly while engaging in physical activity could compress the nerves (not pinch them), leading to temporary discomfort that might make walking difficult. One Australian case study recounts a woman who wore her skinny jeans while helping a friend move. After hours of bending and squatting, she began to experience soreness, swelling, and numbness in her legs. When she attempted to walk home, she collapsed from numbness and had to be hospitalized. Fortunately, she kept her legs and, after several days of treatment, was able to walk normally again.
