This is also from Mama Tad, but as a mix of videos.

Thunderwhat?!

Graystripe woke up with light flashing in his eyes. "OW. Where am I?" The tom opened his mouth wide, tasting the familiar air. "Thunderclan! And I'm in the old forest! I should go to the camp!" He ran to where the scent is the strongest, bumping into his friend, Firestar. He looks surprisingly...young... Come to think of it, the Mistystar he meet before was rather young too. So maybe...Fireheart?

"Hey, Fire-" The orange cat turned at give him an odd look. "-heart? Hello?" The former deputy waved his tail to his former leader's face. "Fire-"

"YIPE! YIPE! YIPE! WHAT DOES THE FOX SAY?!" His friend sung as he rolled away.

"-heart? What is going on this time?" Graystripe shuddered at the thought.

-Reaching camp-

"Okay, everything seems fi- it isn't." Graystripe stated the obvious as Cloudtail...Cloudpaw walked past saying something about "shacarron" and "macaronna" or was it "chacarron" and "macarron"? ...

Graystripe turn to the leader's den to see Bluestar flashing herself with some Twoleg miniature box. A tom sitting next to her, Oakheart?, with a forearm around her smiling. He shook his head as Longtail runs over him.

"I'M A VAMPIRE! I'M A VAMPIRE!" He can hear the older tom yowling except... "Did you just say 'I'm a mad cow?' "

"NO! I'M A VAMPIRE!"

"Mad Cow."

"VAMPIRE!"

"Mad Cow."

"VAMPIRE!"

"Mad Cow."

"VAMPIRE!"

"Mad Cow."

"I'M A VAMPIRE!"

"Mad Cow." The other tom's eyes turn red.

"Arrrrrrrrrrrrrrrrggggggggggggggggggggg! I AM GOING TO BITE YOU!" Just before Longtail could open his mouth, he got punched in the face by a black paw.

"Yellowfang!"

The medicine cat smiled. "Glad to know there's one other sane cat."

"One other? Isn't there anyone else?" The black cat shook her head.

"Mousefur?" *points*

The brown cat was waving her a tail in circle as her hindquarters...

"Sandstorm?"

Yellowfang pointed again. Firestar's mate was standing on two legs while waving her forepaws and tail to a certain amount of time until..."Mom?" asked Leafpo-kit.

"Darkstripe?"

"You have to do it. You have to. Or I'll fire you. Do you understand?" Darkstripe threatened to Brambleclaw. "I don't understand." "I'm gonna have you fired." Okkkay.

"What about Ashfu-"

"A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, AND Z!"

"Nevermind. What's wrong?"

"Why are there two of you?"

"Huh?"

"Hey, Mom, whats a twerk?"

"I'm not your MOTHER! AND DON'T EVER ASK THAT QUESTION AGAIN!"

"Yellowfang, what is-"

"NNNOOOOOOOOOOOOOO, STARCLAN! NO! STARCLAN! PLEASE NO! NO! NO! NOT EVEN A KIT! NNNNNNNNNNNNOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!"

Graystripe backed away from Yellowfang's yowling of Squirrelkit, turning to see what she had looked at. Another him was standing on two legs, while trying out twoleg pelts and using twoleg stuff.

He fainted.

"Hello Leafpool."

"Hi Littlecloud, Mothwing, Willowshine, Kestrelflight."

"Where's Jayfeather?"

"He's staying behind to take care of Graystripe. There's something wrong with him. He can't wake up."

The other medicine cats gasp. Leafpool explained what happened to Graystripe to her friends

"I plan to ask Starclan to walk into his dreams to wake him."

They nodded in agreement and headed to the Moonpool.

"Bluestar! Runningnose! Flametail!"

They dripped their heads to the medicine cats. "Hello."

"I have a request. Can you lead us to Graystripe's dream?"

The Starclan cats look at each other, hesitant.

"Or maybe wake him up?"

"About that, we tried to send someone to wake him up, but she ended up getting caught in it."

"Caught? How?"

"NNNNNNNNOOOOOOOOO! STARCLAN! NO!"

The cats turned to a very loud Yellowfang, yowling her head out.

Cough, cough. There are two Graystripes because there's him and the him during that time period in the dream. There isn't two Yellowfangs because she was already dead during that time. There was only Yellowfang there because she walk into his dream. And Starclan is unable to help.
