Some facts are fun. Some are obscure and historical, humanizing a once alienating and distant past. Other facts, however, or totally unnerving.

Creepy facts remind us that in this world there are natural occurrences and/or particular kinds of people capable of truly horrifying things. Knowing about a strange disease, a grotesque animal, or the motives behind some infamously villainous behavior can make you think twice about walking out the front door.

But we do. We have to live our lives. Though with some unsettling new information on our minds-- thanks to a recent Reddit post--we'll likely do so with a bit more humility and self-preservation.

Vacancier1807 asked, "What are some VERY creepy facts?"

Bone Prison

"There is a genetic disease called fibrodisplaysia ossificans progresiva. When tissue is damaged, it is replaced with bone."

"Growths form underneath their skin and their joints lock solid. So over time those affected slowly become encased in a prison of bone just beneath their own skin."

"They usually have to choose between sitting or standing up for the rest of their life. By the end of their life they have to drink every meal through a straw and can barely move."

-- Sythosz

Hiding in Plain Sight

"Your eyes have a separate immune system from the rest of your body. If they get damaged in such a way that it affects anything other than your eyes, your regular immune system can attack the damage and will not recognise them, meaning your own body can permanently blind you."

"What's worse, your body cannot tell the difference between either eye. If one of them gets infected or damaged, your immune system can attack your healthy eye and take away your sight entirely."

-- TBroomey

Off the Hook

"The Colombian serial killer Pedro Alonso Lopez, who is known as the Monster of the Andes, murdered over 300 girls from Ecuador, Peru and Colombia."

"However, after he was caught and imprisoned for 18 years, he was put in a psychiatric hospital. There he was reviewed, declared to be sane and was set free, in spite of his blatant avowal that he fully intends to kill again."

"Since he was released in 1998, nobody knows where he is or what he's doing. ( He is supposed to be 71 years old at present). He is known for being the most prolific killer ever."

-- ridhan3912

Fate Finds a Way

"The men of the ship Essex (the true event that inspires the story "Moby Dick") avoided islands after being shipwrecked for fear of cannibals. The islands were settled and landing there would have brought salvation to the survivors."

"Ironically because of this bypass, the men ran out of food and were forced to eat each other for survival."

-- BrigettetheNanny78

The Bath Salt Myth

"Remember that bath salts cannibal guy from a couple years back?"

"He wasn't high on bath salts when he did that. That was just media speculation and bullsh**. They only found pot in his system during the autopsy."

"We still have no idea why he flipped out."

-- peezle69

Pragmatic Little Buggers

"One reason that crows and ravens are associated with death is because they would often follow armies as they marched to battle."

"Being both carrion birds and extremely intelligent, they realized that a large group of armed men marching on one direction meant that there would be a tasty meal of corpses to eat soon afterwards."

-- TheEldritchHorror

Conscious CPR

"Imagine being totally aware of someone preforming CPR but you physically can't move or respond. Well that's what happens when you get bitten by a blue ringed octopus, you have approx 6 minutes between being bitten and someone starting CPR to keep your heart and lungs functioning to ensure you survive, all whilst being totally aware of what is happening to you."

"Neurotoxins are fun!"

-- camelsdonthavetoes

Way Too Late to Realize That

"It wasn't until 1987 that the American Academy of Pediatrics declared it unethical to operate on newborns without anesthesia. Until surprisingly recently, the medical community felt it would be dangerous to give infants anesthesia and/or believed that they didn't feel pain." -- allothernamestaken

"Thank god I was born in 1987" -- pandemchik

"I don't think it was because they thought infants didn't feel pain, but rather they just wouldn't remember the pain. Similar reason why circumcisions are given at such a young age, because infants don't remember it" -- DreamedJewel58

Gendered Mummification

"Female mummies in Ancient Egypt were always more decomposed than their male counterparts. They discovered that this was because male bodies were embalmed a lot sooner than female bodies."

"Female bodies were kept at the family home until they started to decompose in order to avoid necrophilia at the embalmers."

-- crossstitchwizard

Whirling Fire

"A Fire Whirl can go as big as an EF3 tornado."

"In 1923, such happened in Japan during an earthquake. The son of a bi*** killed 38,000 people in less than 15 minutes." -- MissSara101

"they got hit by a tornado THAT WAS ON, F***ING, FIRE!"


"thats some scifi super storm sh**. Jesus christ." -- EJX-a

Cast Away

"Rosemary Kennedy was JFK's sister. She suffered from oxygen deprivation at birth and that unfortunately stunted her mental growth. She had a pretty decent childhood, but as she grew older she began to act out."

"Afraid that her behavior would risk his political career, her father, Joseph, agreed to have her lobotomized. Her mother, Rose, was against it and forbade him from doing it. So he did it behind her back when she went on a trip."

"After the operation, Rosemary's already low IQ was lowered even further, to the point she could no longer walk or communicate. Her family had her locked up in an institution and basically disowned her. They never visited and never publicly acknowledged her anymore. Rosemary died at the age of 86."

"Her mother never for gave her husband for what he had done."

-- TheFoolXXIIMaxX

Complex Approaches to Fertilization

"There is a fungus, Cordyceps, that can actually brain-control insects, forcing them to move to a higher location where they will eventually die and release more Cordyceps spores." -- BreakinMyBallz

"I've heard of these things. When they grow out of the ant, other ants will identify it and bring it far from the colony. The ants that bring it out are very likely to be infected, so the fungus covered ant and the other sacrifices will wait there for the rest of their lives to die."

"This keeps the rest of the colony from getting infected." -- NoodlesInPudding

It's All About Taste

"Cannibals find the palm of the hand the tastiest" -- Greymattergone

"is that why whenever you have a scratch on your hand you feel like biting it instead of scratching it like a normal person" -- takis_fuego

Picture It!

"Crocodiles can gallop. Like a horse. I don't like knowing this so I am cursing you people with this knowledge as well. Fortunately alligators cannot." -- SaltyPeanut69

"So THAT'S how you tell them apart" -- zezozose_zadfrack

"Yeah but now I'm confused how to tell a horse and crocodile apart" -- toamke

Various Bears

"I once read that you should play dead if a bear attacks you, unless they start licking your wounds because that means they plan to eat you. That still haunts me to this day." -- xenopants

"If it's black fight back, if it's brown (grizzly) lie down!" -- YogaMom07

"And if it's white, say goodnight!" -- pixiegurly

What a Way to Go

"There's a spider that gives you a 3h long boner, before you die from its bite"

"Edit: the boner it gives you is very painful." -- alien__unknown

"Die hard" -- eatsleepcars

"If it bites you you might as well dick slap it into next week." -- TheSoviet-Union

Sleep You and Awake You

"Most people smell different when they're awake" -- RealSirRoyal

"That's my favorite thing to whisper" -- b_a_b_a_r

"When I started this thread I was waiting for a baby to fall asleep. Said baby is now asleep. I mean, I guess she smells different, but I also want it to be true, so maybe not."

"Also, I woke her with my sniffing, so maybe it went back. I don't get this one." -- NotMyMainName96

Curious about various situations, Redditor Delicious_Mastodon83 asked:

TRIGGER WARNING: This article contains sensitive content about depression and mental health.

As the stigma around mental health lessens (however slowly), people are more forthcoming about the problems they are facing. One of the most common mental health issues is depression.

Depression can affect many different types of people. Factors such as gender, race, nationality, and even age have no bearing on whether someone suffers from depression or not.

According to the World Health Organization (WHO), globally, " estimated 3.8% of the population affected, including 5.0% among adults and 5.7% among adults older than 60 years..."

Depression displays in certain patterns, such as mood changes, physical difficulties, and social isolation. However, depression manifests differently in different people and feels different to different people.

Reddit users divulged what depression felt like to them when Redditor iodineseaspray asked:

"What does depression feel like to you?"

Some of this is sure to sound familiar.
