Nighttime is for horrors and discovering how frightening the world really is. We aren’t talking about ghosts and other paranormal phenomena. They haven't YET been added to the library of proven scary facts. We are here to take a look at the scientifically proven horrors. The ones that we can’t deny or run away from. And unfortunately (or luckily for all you dark copers out there), there are many creepy facts about humans and the Earth we live on.
Human bodies might work in creepy ways, but they can’t beat the frightening things our minds have done. For example, one of the scariest facts on our list touches upon the horror movie Poltergeist. This might come as a shocker to you, but the corpses you saw in the movie — those were actual human remains. With this scary fact in mind, you might watch the movie from a different perspective. Or never watch it again.
However, to truly make your sleep feel more like a nightmare, you should know the dark facts about Earth and its inhabitants. Crows, for example, can remember and recognize human faces. On the other hand, some scary facts touch upon geography. Mount Everest, the highest mountain above sea level, is also the world’s highest graveyard. Approximately 150 bodies are resting on this giant of a mountain. All of whom will likely never be recovered.
Ready to get scared? If so, turn off the lights, cozy up in your bed, and delve into the scary and disturbing facts we have compiled below. Also, we advise you to stick till the end because, throughout the post, we explore how scary facts affect sleep and why the ocean might be the most terrifying place on Earth!

Why Dark Facts Are Scarier at Night?
Horror and darkness mix rather perfectly. Scary facts can evoke terror and horror because that’s simply how our brain works. Creativity plays an important part here because we start to imagine fictitious things. Our minds start imagining things that are simply not there… or are they?
Imagine for a moment a situation. You are in your room, alone in the house. You start reading through some dark facts we have compiled. You brush them off as “goofy” and “not scary.” But your ears pick up noises outside your door. You start thinking, “What was it?”, “Who made those sounds?” and your body trembles. That’s because your brain has been hijacked by fear.
Both horror movies and games work on the same principle. However, scary facts are way more interesting because they’re true to the bone. Thus, if you are looking for a quick pass to a nightmarish night — these facts are the way to go.

How Do Disturbing Facts Impact Our Sleep?
Knowing why disturbing facts are scary, you might want to understand how they impact your sleep schedule. It’s not a myth that horror genre-related stuff (scary facts included) worsens sleep. However, to prove the myth practically, watch a horror movie or read some terrifying facts before sleep. The likely outcome is that fear will kick your fight-or-flight response into overdrive, signaling the body to release adrenaline (if you get scared, of course).
If you missed a few biology classes, adrenaline is a hormone our bodies produce. It’s usually released in dangerous or stressful situations. It activates our “fight or flight” response and keeps the body on high alert. Truly horrific facts, when read at night, will quickly trigger the production of this hormone.
High alert mode can heavily disturb your sleep because adrenaline keeps you up and makes you feel moody and slightly annoyed. So, the next time you decide to read a scary collection of facts, don’t expect to fall asleep early. Just make sure to get around 8 hours of sleep the next day.

More than 80% of our ocean is unmapped, unobserved, and unexplored.

it’s a pretty good thing, when you see the condition of the known areas
How Many Creepy Things Are in the Ocean?
Humans are natural explorers. Thus, something we can’t explore gets shrouded in mystery. The more mysterious the place — the creepier it is. You might not know it, but only 20% of the ocean has been explored. Thus, it’s no wonder why so many creepy things and facts come from this place.
While we might label space as the most mysterious thing, that title goes to the oceans. With 80% of the ocean still unexplored, what we know now is already creepy. For more creepiness, check out creatures found in the deep seas. It’s a guaranteed way to get a mild case of insomnia.
So, regarding how many scary things are in the ocean, the answer is simple — a lot already, and much more hidden. Someday, we might explore 100% of the ocean. By that time, we will be indeed frightened to our cores.

"Brain-eating" amoeba has infected at least 40 people in the U.S. over the past decade. The single-celled organisms go by the scientific name Naegleria folweri, and may infect people who swim in lakes or rivers.
Elena Doyle 3 years ago
And the chances of you recovering from it are slim. Of course, that also depends on when you go to the doctor and they diagnose you. There are three stages of Naegleria fowleri: cyst (1), trophozoite (2), and flagellate (3). If they catch it in one of the later stages… sorry. The amoeba causes an infection that causes swelling in the brain, then death. There are no known treatment that are 100% effective, but according to the CDC, “Recently, two people with Naegleria infection survived after being treated with a new drug called miltefosine that was given along with other drugs and aggressive management of brain swelling.” It’s also really important to be careful what water your swimming in, because the amoeba enters your body through the nose or an open wound I’m pretty sure. A lot of the times it’s lake or pond water. Believe me, this isn’t something you want. Between 1962 and 2019, 4 out of 128 people survived. Please be careful.

“The Devil’s Bible” is a real thing, and it’s a contract between a monk and Satan. Codex Gigas, “The Devil’s Bible” is the largest Latin manuscript known to the world. It contains a full-page portrait of Satan. People believe the manuscript contains the contract of a monk who sold his soul to Satan in the 13th century in order to escape execution.
UpQuarkDownQuark 3 years ago
It’s a large manuscript, all in Latin, containing several books, including the Bible, a medical text, works by Josephus and common prayers. It’s estimated that the minimum amount of time it would have taken to complete it is 20 years. A legend later arose that a monk who broke his vows was sentenced to death, and in order to avoid his penalty he promised to write a book containing all human knowledge in one night, ultimately selling his soul to Devil to help him.

Maggots are perfectly fine to consume, just insect protein. And if that isn't enough for you, the canning process involves very high temperatures that kill anything you need to worry about. And if that still isn't enough for you, insects are actually healthier for you than most livestock. Provided it's cooked properly. Just like livestock.

A body decomposes four times faster in water than on land.

False false FALSE. The process is actually slower, mostly due to lack of oxygen (which helps break down remains) in the water as opposed to on land. Though once removed from water, the bodies decomposition will likely accelerate.

Here’s a silly one: male parrots regurgitate on females they are attracted to. It’s like saying “I’M SO HOT FOR YOU BABE, WHENEVER I SEE YOUR FACE I WANNA TOSS MY COOKIES!!” 🦜💘🤮. . . The science at work here is the bird is demonstrating his ability to be a good provider. He is willingly bringing up food from a storage pouch in his throat (called a ‘crop’) to feed his would-be girlfriend. Regurgitation and vomit are not the same thing in the avian world. A mother parrot can similarly feed babies with food from her own crop. Birds appreciate a free meal even if it’s been pre-chewed for them!
