Imaginary Nemesis || A Gravity Falls Oneshot

One shots of my original AU.

"Why do I even listen to you!?" He yelled, his voice carrying through the empty house. He crumbled to the ground and put a hand over his throbbing eye,
"You aren't real."
"You were never real...It's just me...I've done this to myself..." he had never realized that if Cipher wasn't real...this was him.

Basically an AU where nobody knows Bill Cipher is real. Dipper has been diagnosed with Schizophrenia because he hears "Bill" all the time. His parents send him and his sister up to Gravity Falls after finding out his Great Uncle Stanford had heard and seen voices and visions before, though not for the last thirty years...

I feel like the 'Bill is Dipper's imaginary Friend' has been done before?? I haven't read it but maybe I've read a synopsis?? I really hope that if it has been done before that it's not too similar! I didn't mean to copy! This ain't Billdip so if you don't like that me neither lol. I own nothing.
