Bill Cipher stared outside at a hospital.

"Hey, boss!" called 8-Ball. "What are you doing?"

Bill shrugged. "Eh. Just thinking." Bill went on even though 8-Ball hadn't asked. "I was thinking about how high we are above humans." He chuckled. "I mean, humans get injured and sick, but we don't have any of that. And can you imagine a human trying to fight me without any sort of weapon?"

"Aren't you friends with humans?"

"Yeah, good point." I'm still more powerful than them, though, he thought.

The next day, Bill felt very strange. The top of his triangle ached badly, and he felt nauseated. He couldn't stop shivering, and he somehow fell asleep.

Meanwhile, the demons flew over to the Mystery Shack to get help for their boss. Kryptos knocked on the door, and Stan opened it.

"Hi!" chirped Kryptos.

"What do you want?" asked Stan impatiently.

"Bill's been feeling terrible," answered Kryptos. "We need someone to help him."

"All right," replied Stan. "Give me a sec."

Stan went back inside and came back with Ford. "So, something's wrong with Bill?" asked Ford. The demons nodded. "What happened to him?"

"Well," replied 8-Ball, "he keeps shaking, and he was in pain before he went unconscious. Oh, and he feels sick."

"Okay," replied Ford, confused. "Let me see what I can do. Can you take me to him?"

Xanthar walked over to him and lied down.

"Okay, then. Let's go see what's wrong with Bill." Ford climbed on, and Xanthar reared and bellowed deeply before he and the other demons flew to the Fearamid.

Bill was in the corner, shaking but otherwise looking like he was asleep.

"Bill?" called Ford. "Are you okay?"

Bill's eye flipped wide open with a gasp. "Oh, it's just you."

"Your demons said there was something wrong with you. Mind if I take a look?"

"Sure."

Ford tried checking him for a fever. "What's the normal body temperature for a demon?"

"I don't know," Bill retorted. "I never checked."

Ford sighed and tried checking everything he could, but the diagnosis was hard since he didn't know what was normal for a demon.

"Okay," said Ford once he had gotten all of the readings, "I think I have an answer."

"What is it?" Bill asked lazily.

"Assuming you are physically more or less like a human... I'd say you have the flu."

"You mean I'm sick? That's ridiculous! I don't get sick because I'm not a human."

"You have a physical form now," Ford pointed out.

Bill was about to retort, but he realized Ford had a point. "All right, fine, I'm sick. So what do I do about it?"

"Well, you should drink plenty of fluids if you can. And get plenty of rest."

Bill's eye widened. "You mean sleep?"

"Yes. Is that a problem?"

"Uh, no, of course not."

"Are you hiding something?"

Bill let out a long "Maybe." Ford just stared, waiting for Bill to give a genuine response. "Okay, fine. I don't like sleeping much."

"Well, you'd better get used to it if you want to get better."

Bill groaned with reluctance and tried to sleep.

"That's better," replied Ford before leaving.

The demons were filled with concern again, however, when they saw Bill twitching in his sleep.

"Should we get Six Fingers again?" asked Keyhole.

Ford came back, this time with Dipper and Mabel because they wanted to help.

"He looks pretty freaked out," Dipper pointed out.

"Think he's having a nightmare?" asked Mabel. "Do demons have nightmares?"

"Not usually," replied Pyronica, "because we don't usually sleep."

"Well, he looks like he's having a nightmare," said Mabel. "I wish we could see what he's thinking."

"Hmm," said Dipper. "That's it! Grunkle Ford, do you have Journal 3?"

"Yes. Why?"

"You know that incantation used to follow Bill into the mindscape? Maybe we could use that to see what he's thinking."

"Yeah!" exclaimed Mabel. "Looking at how distressed he is, I'd say it's worth a shot."

"All right!" said Dipper. "Everyone, put your hands on Bill's head... or... something."

As Mabel, Ford, and the demons complied, Dipper recited the incantation: "Fidentus omnium. Magister mentium. Magnesium ad hominem. Magnum opus. Habeas corpus. Inceptus Nolanus overratus. Magister mentium, magister mentium, magister mentium!"

Then, they were in Bill's mind.

Okay, my first two-parter in this fanfic! The idea of Bill getting sick was requested by C.C in a review. So, I guess I'll end the chapter here. Stay tuned for Dream Demon Part 2!
