The National Institute of Mental Health suggests that phobias affect approximately 10% of U.S. adults each year. They typically emerge during childhood or adolescence and continue into adulthood (and impact twice as many women as they do men).
So when Reddit user Aelmnnor asked everyone on the platform to share scientific facts that creep them out, they received plenty of answers, and the post eventually turned into a nightmare fuel tank. From microorganisms living on our bodies to powerful cosmic events, here are the things that people wish were a lie but, sadly, aren’t.

Basically the entirety of pregnancy/childbirth. Like, this other living organism embeds itself in the lining of my uterus, feeds off my blood, makes me grow an entirely new organ (the placenta) just to feed/protect it while it grows, then it comes out while basically still gestating (other mammals babies can walk and run within minutes of birth, ours can’t even hold up their giant domes!) just because the hole I have to push it through won’t be big enough for its head if it stays in any longer.
Oh, and once I’ve done all that I get to have the longest and worst period of my life while my uterus sheds out 40 weeks of uterine lining.
I’ve had a kid and it still f***s me up.

Honestly nothing is more creepy than how deep sea anglerfish mate.
The deep sea is dark, and the anglerfish are spread very thinly. Therefore, when an anglerfish meets another anglerfish, it’s incredibly important they get the chance to mate over and over again. The evolutionary strategy that deep sea anglerfish devised is extra creepy. The male latches onto the female, biting her and never letting go. That way he can inseminate the eggs she drops. Not that bad so far right? But wait, how does he eat if he’s latched on his mate?
Well, the circulatory systems fuse and the female provides nutrients for the male through this fused circulatory system. The true horror starts here. The organs of male start to wither and atrophy, being absorbed into the female. Eventually, the male is reduced to a lump of testicles the females use to fertilize their eggs. Females are often covered in bumps of several males that have melted into the female, becoming a literal body horror lump of meat on the female.

Your brain literally creates your own reality and your senses and body just go along with it.

People think the brain sees what the eyes tell it to, but really the eyes pull up an image of blurry colors and dark spots and the brain goes “cool so that’s a tree”

The mantis shrimp can see colors that our eyes aren’t capable of perceiving.
Think about that.
What else are we just not capable of sensing?

When you go to get something from one room (or upstairs) and suddenly forget why you went in there. It’s called a boundary event. Usually, if you go back to where you started (through the boundary) you’ll remember it again.

The universe is unbelievably infinite, while simultaneously unbelievably infinitesimal.
The universe has ~10^22 stars, a rough guess. This is an unfathomably large number for humans to comprehend, but bear with me. There is roughly 100 thousand million stars in our galaxy alone, and there are roughly 125 billion galaxies.
A single drop of water contains ~10^21 H2O molecules, not too far off from the number of stars in the whole universe. A very similar number, but contained in a single drop of water!
It blows my mind that the universe can contain such mind boggling numbers of things on such wildly different scales. There is so much to reality that the human mind just isn’t capable of grasping.

If you believe strongly enough that you have been cursed, your brain can shut itself off entirely in severe cases. The psychological term for it is “Voodoo Death Syndrome.” It’s just the fact you can literally think yourself to death that unsettles me so.

Caterpillars turn completely into goo in their cocoon, and then become a butterfly.
MarnerIsAMagicMan added:
And there is evidence they retain memories from their pre-goo days. Memories of strong positive/negative stimuli that they show preference-for/aversion-to, even after metamorphosis.

That so many vegetables came from the same plant. Broccoli, kale, kohlrabi, Brussels sprouts, cabbage, etc. They are, botanically speaking, the same species. Humans have just bred them to emphasize different traits (buds, leaves, tubers…) Imagine if humans were as genetically flexible. Imagine a person walking around with GIANT toes, but otherwise normal.
Actually, plant genetics in general is a weird, weird world.

Humans are bioluminescent (nothing to do with body temperature). We emit visible light that can be photographed in specific conditions. But, this light isn’t visible to us. Which makes it a strange thing to have evolved, and begs the question
“what organisms is this light visible to, and why?”
Edit: Adding an edit for all the comments explaining evolution… Please read the thread before commenting. I find this a creepy fact due to implications on interspecific relationships, NOT because I think prehistoric humans went shopping for a bioluminescent hat with a specific motive in mind.

The brain can play tricks on you:
When you look at a clock and the second hand seems to freeze for a moment, your brain is actually generating a false memory – and your perception of time stretches slightly backward.
This effect is called chronostasis.

Parasites can live anywhere inside of you, for years unnoticed. A simple migraine could be a tapeworm crawling in your brain, causing damage.
Your eyes begin to blur frequently and you don’t know why and it’s not getting better.
Losing weight and having diarrhea but it’s not a stomach bug. Well, I guess it is…
You are having a difficult time catching your breath and your chest doesn’t feel right.
It could just be some parasite hanging out, using you.

Not exactly scientific or creepy but, it’s close enough and I want to contribute.
Mouth pipetting was a thing in labs in the 1980s. A pipette is, for simplicity sake, a glass straw that lab staff would use to transfer liquids. Now a days we use special bulbs, that when squeezed, would suck up the liquid for us. Kinda like a turkey baster or eye dropper.
Before we had these bulbs lab workers had to use their mouths to suck up the liquid. Which meant if they weren’t careful they’d get whatever they were sucking up in their mouth. I’m currently training to be MLAT and those fluids would usually be urine, liquid stool, sputum and so on.
Edit: So mouth pipetting is still a thing. I’m Canadian and I’ve been told that it is rare or none existent in our labs.

Obligate siblicide. In some species of animals, multiple offspring are born but only one is actually raised by the mother. The others are born only as backup in case the first-born doesn’t survive. When the first-born is fine, which is the typical case, it kills the others.

Years ago I saw an episode of *Monsters Inside Me* where this guy was doing something outside and a fly flew into his eye. It only made contact for about a microsecond, but it was enough time for it to lay eggs. After they hatched they started eating his eye from the inside and he was starting to go blind until a doctor figured out what was wrong.
Just imagine that, getting your eye eaten from the inside and losing your sight all because a fly *very* briefly made contact with you. Ever since I learned about this I get really paranoid when there is a fly around my face because of the fact that this could possibly happen to me.

– Out of all our DNA, only 2% codes for our genes.
The 98% leftover is called “junk DNA”. I’m not specialised in genetic, but it was long thought to be useless but it’s apparently essential for DNA expression regulation and protein formation.
– There are familial forms of alzheimer’s disease. They are very rare but they exist, it doesn’t skip a generation and one of the form makes you have the disease as early as your late 20’s/early 30’s.
– In Auschwitz, Joseph Mengele, a nazi doctor who conducted experiment on twins, sewed up 2 twins together for sh**s and giggles and let them die after the surgery of infections. They apparently screamed of pain for days until dying.
– You can live “normaly” with half your brain removed. It’s usually done on young children suffering from terrifying epilepsy and the surgery is the last resort. It works quite well and if done early enough, with reeducation, the children develop normally without cognitive deficit, they “just” are blind from one eye, have one very weak arm/leg but they are not cognitively affected : some go to college, get married, have children and live completely normal lives.

Here’s a good one: your eyes are an exposed extension of your brain.
In other words, and apologies if it sounds a little sociopathic, but if you take apart your head piece by piece with just the brain in tact your eyes would be dangling from the brain. Or, you can just google “eyes and the brain” to see what I mean.
