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).

ADVERTISEMENT

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.

"Somniphobia is the extreme fear of sleep. People with somniphobia may worry or obsess throughout the day about how they can avoid sleep. They may be afraid of what happens when they do fall asleep, such as having a nightmare or sleepwalking."

30 Scary Facts That Will Give You The Heebie-Jeebies More than 80% of our ocean is unmapped, unobserved, and unexplored.

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.

ADVERTISEMENT

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.

I put my back out trying to contain a sneeze. It was so painful that I had to crawl very slowly into my bed. Thankfully, I was ok after a few days, but I won't be doing that again!

what's really weird about Cotard's is that it can seemingly appear out of nowhere and then go away on it's own. That it to say, there is obviously a medical reason, it's not witches, but we just don't know)
