(Bill's P.O.V.)

Dipper Pines, a 12 year old boy with a twin sister, and has a crush on a girl. I've been watching the kid ever since he got here. Now, I have my chance. I hovered over to him when he was sleeping. Then, I entered his mind, and into his dream.

This kids mind was full of different things. It was quite disturbing to be honest, and there was nerdy stuff everywhere. I didn't even know what to think. We were in fact in the extra room in the shack, where some girl was asleep.

Then, I found him. He was sitting down looking around, probably confused. "Hello?" He called out. "Why am I here in Autumn's room?"

I teleported in front of him as a huge glowing light appeared. "Hello Pine tree." I said to him. Before I knew it, he was screaming. "Whoa kid, there's no need to burst your own eardrum out."

"W..who are you? And why did you take me here?" He asked looking paranoid.

"The names Bill Cipher, and you are Dipper Pines."

"H..how do you know my name?" He asked pacing back and forth.

"Oh, I know lots of things kid!"

He stared at me like I was insane. I right, I am insane! "Listen kid, I heard that you are new here to Gravity Falls. I've been keeping an eye on you lately, and I have to say that I'm impressed with you and your sister."

"Wait, no. You can't be! What are you?" He asked focusing on me now.

"I am a dream demon, and I have a job for you. It's really important."

"What is it?" he asked looking suspicious.

"I need you to summon me, and if you do, then I could tell you all the secrets and mysteries of Gravity Falls. I might even tell you the author of the journal..." I continued, but he interrupted me.

"Wait, you could tell me everything!? All the secrets about Gravity Falls? And the author?! This is amazing, I can't believe this!" He sounded pretty happy, but not for long. But then everything started to fade. "Hey Bill, what's going on?" He asked.

"Sorry kid, we'll talk later, but remember, Reality is an Illusion, the Universe is a hologram, buy gold!" I said, and then I teleported away.

(Dipper's P.O.V.)

I woke up gasping for breathe from all the excitement. I couldn't wait to tell Mabel what I saw. I ran down the stairs with journal in my arms, flying through the pages. "Mabel Mabel! Guess what I dreamed about last night?" I said jumping off the last step.

"Puppies and rainbows!" She replied bouncing around.

"You wish Mabel!" I flipped to the page named 'Bill Cipher' "Look at this thing. He is a dream demon and I dreamed about him last night!"

"Dipper, that doesn't sound really normal. He's a dream 'demon'. What did he say?"

"He said that if I summoned him from this book, then he would tell me all the mysteries and secrets about Gravity Falls. I'm so excited!" I replied.

"Dipper, does that sound safe to you?" Mabel said before walking out of the room. Then Autumn came from the kitchen. "Hey Dipper, what's up?"

I froze. I couldn't say anything. I immediately closed the book and put it under my arm. "oh hey Autumn! I..I"

"You alright?"

"Yeah I'm fine! Perfectly fine!" then I ran upstairs and shut the door, locking it, behind me. "Oh Dipper, what are you going to do?" I said to myself. I looked inside the book, reading the 'Bill Cipher' page. How could I not realize it? In the right bottom corner, big bold letters shone, Do NOT summon at all costs! Why didn't I see it before? I kept reading, "Beware Bill, the most powerful creature I have ever encountered, whatever you do, don't let him into your mind." I said aloud. If I haven't of seen that, I would have been in big trouble.

Then, an orb of light began to form, just like in my dream. As the light faded, Bill hovered over to me, with his cane in his hands. "You! You lied to me!" I yelled at him. He looked awfully confused.

"Pine tree! I would never!" He crossed his arms letting go of his cane, as it floated in mid-air. I looked around the attic. Everything was a light shade of grey. "Bill, admit that you lied to me! I can't believe you did that!"

Bill stood there shocked, "Well pine tree how would you know if I'm lying or not? Hm?" I opened up the journal, flipping to his page. "Bill, you're dangerous, and I'm not supposed to summon you. Go ahead, haunt all of my dreams! It's not going to stop me so I could summon you!" I slammed the book shut and everything turned back to color. Bill disappeared without me looking.

Mabel walked up the stairs. "Hey bro bro! Whatcha doing up here?" I turned around holding the journal behind my back. "Oh uh, nothing!" I said, feeling my eye twitch. Mabel had a blank expression. "Oh, uh okay..." she said walking back downstairs. "Come on! Grunkle Stan said he want's to throw a huge party today!" I immediately straightened up and put the book on my bed.

"We'll talk later." I said running down the steps.
