is it a creepypasta or something else?

Darkness.

That's all I could see,I couldn't feel anything,much less move.

"Am I dead?" I sead

"you aren't Jay, but that all depends on your answer to a particular question." A voice very familiar to me but I can't put my finger on it.

"Who was that. SHOW YOURSELF"

"Very well"

With that sead a strange horse appeared out of nowhere next to my head so I could only get his facial features. He or she had massive cobalt eyes that had a bored look to them, a grayish amber coat and a messy dark gamboge mane.

"Hello I am Time Turner or as you humans refer to me as Doctor Who I don't have much time so im going to get down to the point. I need your help with correcting the timeline so the world I am currently residing in doesn't cease to exist. I am going to send you back before 'it' happens"

"Wait hold up your world is Equestria correct?" He nods "and need me to go correct your timeline?" he again nods

"What is the 'it' that got the world destroyed in the first place?" i asked

"I am going to have to give you the small version. Basically Rainbow Dash that is in my world is the creepypasta 'rainbow factory'and she went mad with power. She was so powerful even the princesses couldn't stop her."

"What do you expect me to do then!?If the princesses failed what do you expect me to do? I am only 1 human you need a full on armada to stop her." As i was talking Turner looked like he was pressing something, I know this because every time he puts his hoof down a beep like noise would sound off. Finally when he was done with that he started backing up.

"Well that may be true, But sometimes to sooth a nightmare you must be a nightmare."

"What do you mean by-" I couldn't say anything else because I fell into unconsciousness.
