=== The day was June 29, I was editing my video. When suddenly my classmate called me on WhatsApp. He asked if I could play Minecraft with him. ===
The conversation went like this:
Him: Hey, how are you?
Me: Fine, I'm editing my vid, the rendering is at 89%
Him: Ok, can you play Minecraft when you finish?
Me: K, Modded or Vanilla?
Him: Modded, Mods such as tinkers construct, divine RPG.
Me: Sure, but first the rendering needs to be finished.
15 minutes later.............
Me: Yay it's finally complete.
Him: Okay
Me: Let's watch the result. *Starts the video call*
Me: WHAT THE HELL the quality is bad I ACCIDENTALLY SET IT TO 240p.
Him: I see, now let's play MC I guess.
We installed the mods and started the server. We started mining some resources and building our base. 
It was at this time that we started to notice some strange things.
First of all, the items that were stored inside our chests were gone. We let it go, thinking it was just some sort of bug or a glitch.
We were trying to find some diamonds when a strange ore block appeared, a black one. My friend tried to mine it but couldn't. None of the mods we had included that ore. It was purely black.
Some time passed by..
We found a giant mine that was very deep and had long 10 x 10 tunnels.
When we were at the middle of the tunnel, we found a book that had the letter "A" written in it, which looked like this: A
I was totally confused.
Me: Bro, are you trolling me or something
Him: Nope, I don't even have the operator thing or any sort of cheats. *He even shared a screenshot with a list of mods he had*
Me: Then what is going on here?
Him: I don't fricking know ._.
Me: Looks like a link, wonder what happens if i click it.
Him: DON`T, IT MIGHT BE A VIRUS!!
Me: I have Arch Linux on my machine so nothing bad will happen.
Him: Ok...I warned you.
I clicked the link. Suddenly, the terminal opened with a command pasted in.
I quickly closed the terminal and alt+shifted back to Minecraft.
Me: DUDE YOU WERE RIGHT I ALMOST GOT A VIRUS.
Him: Never click any link that looks suspicious, k?
We were adding some finishing touches to our base. When I spotted a black figure on a hill nearby.
I asked my friend if he could see this figure, too.
He said: Yes, dude did you join from an alt?
Me: NOPE, DUDE WTF IS HAPPENING?
Him: IDK, Let`s go see.
Me: ooookkkkk.....Let's pray nothing bad will happen
When we checked it out, there wasn't anything at all.
The minute we returned to our base, I got kicked outta there for no reason.
When I tried to rejoin, everything was one big glitch.
The game froze for couple of seconds.
I had a strange feeling. Was another player on the server other than us, or is it just my imagination?
Somebody named Error8372812 started to send cryptic messages in the chat.
<Error8372812>: Warning! Modification of these files could lead to an unbootable system.
<Error8372812>: Never trust anybody.
<Error8372812>: You are alone.
<Error8372812>: Are you even still alive?
<Error8372812>: Error 9459 - Player not found
Error8372812, or whatever it was, teleported us to some kind of corridor. I tried to escape, but the door was locked.
I can minimize Minecraft to give myself operator. But strangely, I couldn't.
"What the hell?" I said. The strange silhouette reappeared. Its name was Error8372812.
My computer shut down.
I tried to boot it up but it wasn't working.
The only thing that was shown on the screen was: ERROR: Binary not found - Load.efi.
Suddenly it started to boot as if the problem was simply a minor technical difficulty. I came back into the server and we continued playing the game.
We were teleported to same room again. But this time, there was a object frame that had a music disk in it.
I put it into the jukebox that was near to the door. It sounded like it was from a R-rated horror movie.
I heard a knock on my door IRL. And I also received a notification from the Ring Doorbell app installed on my phone.
I opened the photo. There was a man wearing a black jacket whose face I couldn't see. I made a mad dash to my bathroom and locked the door.
There was a noise, footsteps, coming from downstairs. Someone was in my house...
I quickly called the police for help, however they said that they will probably arrive one hour later at the least.
When the police finally got here, the only thing they discovered was a gaming computer with a glitchy Minecraft on and a phone that had WhatsApp open. No people were found in the house.
The whole story was even publicized on TV. But nothing and no one was found..........
