Someone asked for ‘creepy facts about the human body’ you’ll never forget and these 9 will haunt your fevered dreams
It all started when @tessysmitha went on Twitter to ask people to share the ‘creepy facts’ about the human body that you wish you’d never found out.
What’s a creepy fact about the human body you wish you never found out?

And while it prompted the odd mildy interesting response, like this one.
The people you see in your dreams are real. Your brain registers and stores faces, but it isn’t capable of generating new faces. So when you see a face in your sleep, it's probably a real face you've seen before.

And this one.
Your brain often makes decisions seconds before you’re consciously aware of them.
Meaning that feeling of “I chose this” is sometimes just your mind being notified late. Bonus nightmare: your gut has its own nervous system and can influence your mood without permission.

There was nothing – absolutely nothing – to compare to this one, a ‘nine for the price of one’ treat which we haven’t stopped thinking about since we read it.
1. Our skeletons are wet.
2. your nose is ALWAYS in your line of sight, but your brain ignores it
3. When you receive a donated kidney, they don’t take out the bad one. They just add the good one in.
4. Your immune system doesn't know you have eyes. Otherwise, it would attack… https://t.co/iNeE35gsIL— Oluwatimileyin✨ (@Timmysofine) January 6, 2026
And those nine in full!
1. Our skeletons are wet.
2. your nose is ALWAYS in your line of sight, but your brain ignores it
3. When you receive a donated kidney, they don’t take out the bad one. They just add the good one in.
4. Your immune system doesn’t know you have eyes. Otherwise, it would attack them and make you blind. injuring one eye can introduce eye bits to the bloodstream and basically give your immune system the knowledge of having eyes. then it might decide it really fucking hates that and attack your non-injured eye.
5. The quality of the male sperm is responsible for morning sickness, preeclampsia, baby’s gender and almost every single pregnancy related issue.
6. You breathe through one nostril at a time. Don’t believe me? Put your finger below your nose and try.
7. The brain itself has no nerve endings, so it can’t feel pain. That’s why patients can be wide awake during brain surgery and made to perform certain actions.
8. That ringing in silence isn’t silence
When everything is quiet and you hear a faint ringing?
That’s your brain listening to its own nervous system.
You are hearing yourself functioning.9. You will never experience your own death.
You only experience approaching it… Then nothing.
Everyone else gets closure, stories, funerals, and memories.
You don’t.
You never know you’ve become a memory.
From your perspective, the story just stops mid-sentence.
Absolute ooof.

“I opened this app for vibes and left with an existential crisis.”

The last paragraph is haunting.
So when we are old and go, we just stand there looking at people wailing and we can't ask then why they are wailing.
May we find and fulfill purpose in this life.— p e t e r (@3xPierre) January 6, 2026
The very definition of ‘be careful what you wish for’, that.
