Insanity or Normality ? BillDip ?

"Bill..." Dipper stood there.
There he saw Zane and Bill. Standing next to each other. Bill had all these charms on him and had a black goo on his arms but he was over the barrier. He crossed the barrier and was now in range of Dipper.
Dipper had to put Mabel down before he sprinted towards him, tackling him to the ground.
Bill laughing and both tearing up, "your here, I can hug you, I can kiss you, I can stand next to you,"
"Not even after death, our love will win, these are just obstacles."
Bill whispered in his ear, Bill lifted his head to see shooting star and llama? But her eyes were purple?
"Who are you?" Bill spoke.
The possessed Pacifica smiled, "hello, I'm Killian Cipher, and I'm in the wrong time period..."
Dippers eyes snapped open and he looked back at Killian in a flash, "Is that what you meant as 'you haven't met me yet'"
Bill just turned his head, purple eyes?
Everyone in his family had there own colors, his father being black and his mother bing white. Leaving Will with blue, Kill with red and himself with yellow. Not to mention the sisters.
"Light your hand." Bill's voice was low, Killian froze and grinned slowly while letting his hand.
There in his palm was a purple flame.
"Hmm....your eyes match your flame, very-"
"Powerful and unique, I know. My father use to tell me that all the time, said I was born to create and destroy."
He looked at Mabel, "alright stardust, seems just as confused as me, may we get a breather."
Bill nodded and watched Killian and Mabel sit down in different trees.
"Is he in your family tree?" Bill heard Dipper spoke. Bill squinted, this was Pacifica's body, but not the soul entirely.
"Like he said flame and eye color matching pretty powerful and unique."
Bill's thoughts were turning until Zane pulled them out of there breaks.
"Aren't dream demons suppose to have the colors of their parents?"
Dipper looked at Bill.
Bill only thought of two demons in mind, Will and Kill. "Maybe my brothers had some fun with some demon in the near future and had him. He did say different time, not a different world."
Dipper only sat there, he didn't understand the situation but understood that once he clears his mind of everything, somehow it'll make since.
"Is there a way to send them three out of Gravity Falls?" Mabel spoke to the albino.
"A way to get these three to the other side? Why if course it's the same process we used to get him in!"
Dipper looked at Zane, "good cause we need a way out, and fast."
