What's going on?

???:Hello there human.

What? I saw a tall figure.. A skeleton?

That skeleton in my dream!

Y/N:Do i know you?

???:Yes, infact i have been creating the world around you since you came to the lab.

Is this a joke?

Y/N:Is this a joke?

???:No.

Alphys:O-Oh! H-hey Y/N!

Y/N:Alphys?

???:Allow me to introduce myself, my name is GASTER. I am the royal scientist.

Y/N:I thought that was Alphys?

Gaster:That was in your little experimental world.

Y/N:No. .

Gaster:Yes. If you wish to see proof, Frisk is still asleep-

Y/N:Wait wait wait, wait a second.

Y/N:So, you are the guy i saw in the dream of my ''experimental'' world?

Gaster:That wasn't a dream, you were just waking up.

Y/N:I saw 3 people tho! 

Y/N:You,Alphys and another human!

Gaster:Oh,you want to see the person who narrated the world around you?

Y/N:I knew something was off!

I saw someone getting out of the door near the crack that Mettaton did..? Wait a minute! Wasn't that a dream too!?

???:Oh great, he woke up!

Y/N:That human is the one that i saw!

Gaster:Their name is-

???:Chara. My name is Chara. And i'm not a human anymore.

Y/N:W-What?

OH.MY.GOD what is happening?!

Y/N:... No shit, you're clearly a human!

Chara:I am no-

???:AAAAH WHAT!?

Y/N:FRISK!?

Y/N:WHERE'S SHE!?

Sans and Frisk came out of the room where Chara came from.

I'M SO CONFUSED WHAT THE HELL?

WHAT'S GOING ON!?

Frisk:Y/N!

Frisk hugged me, i can feel her heartbeat.. She's scared.

Y/N:Frisk!

To be honest, i am scared too.

Y/N:SERIOUSLY CAN SOMEONE TELL ME WHATS HAPPENING!?

Chara:Lemme tell you in a way you can understand.

Chara made a knife appear out of thin air WHAT THE F-

Chara:You were in a God Damn simulation. And i was narrating the world around you.

Y/N:OOOH so you were the person that i called BRAINDEAD upstairs!

oh GOD WHY DID I SAY THAT SHE'S POINTING HER KNIFE AT ME.
