The town where I am the only one missing (Blinded AU)

The Dream

When Dipper opened his eyes, he found himself in a black and white attic, with two beds en each side, the one in the right side was covered in posters and the other was covered in papers of theories, and in between a triangular window with an eye; Dipper found this very familiar but he couldn't place where he was or why the room was black and white.

He started to walk around the room when a blue light blinded him temporarily, he heard a maniac laugh in the air, and once again felt it extremely familiar. The light ceased off, in front of Dipper there was a yellow triangle with an eye, a black bow tie, and a top hat with "Hello Pine-tree!" Saluted the triangle, Dipper couldn't figure out how the triangle could talk but decided not to care "Who are you? And who is Pine-tree?!" Asked Dipper freaking completely "jeez, calm down kid" stated Bill turning around -he doesn't remember everything- he thought -maybe I can use him, in a way- he putted his hand below his bow tie, he smirked in his mind -I will use him, I will gain his trust and when the weirdness starts I will make him betray his family, that he doesn't remember- the dream demon thought and turned around to see the scared looking boy.

"Who are you?! repeated the boy, demanding some answers "Name is Bill Cipher" presented the demon "and yours?" Dipper couldn't answer because he didn't know his name "I-I don't know" he admitted lowering his head, Bill stared at him for a moment "im going to call you pine tree, then" Bill stated "pine-tree?" Questioned Dipper "well... I really don't have any reasons but I think it suits you" admitted Bill, Dipper nodded "why are you here? What do you want from me?" Again Dipper questioned "I want to make a deal with ya!" Stated Cipher, Dipper was eyeing suspiciously I know that I know him but I can't remember him Dipper thought, he looked at Bill in the eye "what kind of deal?".

"What kind of deal?" Repeated Dipper suspiciously still looking at Bill in the eye, Dipper was studying the triangle very carefully "it's and easy one!" Said the triangle "I'll help you to regain your memory and all what you want and you'll help with a thing I have been working on for a while" Bill explained the deal. Dipper thought about it for a minute, trying to decide what to do, he didn't trust the triangle in front of him but he REALLY wanted his memory back and he wanted all the help he needed even to accept help from a flying dorito could help to an extent "tick, tock, kid" explained Bill holding out a hand with blue fire in it, Dipper hold out his hand with hesitation to the blue fire to find out it didn't burn "it's a deal!".
