So the big question at the end of Gravity Falls episode: “Not what he seems”.
Lets take a look at it.
At first, it connects into space. Which explains why the gravity started getting messed up.
But when it connects into the side the author is located in, it goes blue, but then starts to clear and we can’t see feint boards of wood like from the inside of a house.
Now it could just be the blue flare that is causing a color distortion, but to me that looks like a grey inner shack of some sort. But wait… grey scenery? That happens every time a particular demon appears.
But wait- what else is grey?
What’s interesting here, is that a grey scenery so far has something to do with a mind-scape dimension that Bill seems to be trapped in. The only way he can appear is that if everything around him freezes in time, bringing the person/people he is talking to into HIS dimension, like with Gideon and Dipper.
Something also notable, is that there is a strange rubix-cube scene in the attic where Dipper and Bill make a deal.
That rubix-cube suddenly appears when Bill brings Dipper into his plane of dimension. What could this mean?
Was the author not trapped on another world, but rather in another dimension?
Its highly likely.
Now I’m going to bring to attention this:
“Reality’s an illusion, the universe is a hologram, buy gold, bye.” - Bill
Reality is an illusion? Is reality actually the mind-scape? And if the portal brought us from space and then suddenly turned into a portal to the mind-scape, would the universe technically be the hologram of the true dimensional mind?
It may seem like a stretch, but I can’t help but feel that all of this connects somehow.
