Life can be scary, and a lot of times we push certain fears aside just to get through the day. But when those fears show up as undeniable facts, they hit a bit differently. Just like a small fall on the ice can remind you how fragile the human body is, a quiet moment under a sky full of stars can make you suddenly aware of how tiny we are in the universe.
A Reddit user recently opened a discussion on facts that genuinely scare people, and the answers spanned the cosmos, the body and even everyday routines.
We picked the ones that really stood out… see if they get you thinking too.

Where I live, you might die a horrible death after being tortured just because you were at the wrong place at the wrong time, and your body would just disappear, your family would not see you ever again, and the government would do nothing about it, but take your death just for the statistics and blame it to past administrations.
And to make things worse, if your family try to push your case, even if it's just to find your body for proper burial, they might get k****d too.
It's a horrible thing.

Babies cry in the womb. We have observed through ultrasound all the classic signs of crying like heaving chests, quivering lips, opening mouths. All the movements made when a baby cries, but it cant because their lungs are full of fluid.
Also babies are covered in a fine hair called Lanugo that is shed before and sometimes after birth. At the same time, the digestive system starts working some time around 7 months. Know what the baby eats and drinks? That's right, amniotic fluid and it's own body hair. Where does all that go? It pisses and s***s back into the amniotic sack, only to drink and eat all that again.
Also it's *Loud* in the womb. Not only does sound transfer way better in fluid than it does air, but the late-term uterus is pretty close to the heart.
So for a couple months before you were born you were trapped in a pitch black fluid prison, screaming silently, drinking your own p**s, eating your own s**t, and the entire time it sounded like someone was trying to beat down the door 24/7.
The miracle of life yall.

There’s nuance to this, so I’m just going to post what I was told.
Your eyes and your body have two separate immune systems. They both have no idea the other exists. If your body finds out you have eyes, it will attack them as if they are foreign objects.
That, and a solar flare could cook us at nearly every moment.

There is an unbroken chain of evolution and successful reproduction extending from the very first form of life right up to you.
If you don't have kids, that chain ends with you.

While some of these facts may shock us and others might fade from memory, they might also open a door to wonder. Realizing we are a part of this big beautiful Universe, and confronting these truths, can give us a deeper sense of meaning.
As Dr Jesse Preston, Associate Professor in the Department of Psychology at the University of Warwick, believes: "Science can be a powerful source of awe and wonder for many… It can foster a sense of connection to others and our place in the world.”

Nobody experiences true reality. We experience a story that our brain has invented a split second after true reality happens.
If those signals were produced some other way - dream, simulation, hallucinations, or misfiring neurons - you would have no method to detect it.

You are never 100% safe. Even if the danger is an extreme one, it could still happen. You're not safe in you're bed, in your house, at your work, nowhere. You will never be 100% safe.

There are millions of tiny microscopic bugs that are crawling over your skin. They're always there so you leave a lot on the pillow while sleeping. That means you put your face on a graveyard of dead bugs and your skin bits. Since I know this I change my sheets way more regular than before.
