Quote from Conversations with Harvey, Episode 14:
26:11 "He sees me. He sees the clothes I'm wearing. He sees me sitting in this chair, and he can sense all the people around us. It's a lot of people around us. And you the audience are looking at that chair and saying it's empty, but it's not empty. Okay, this physical chair doesn't have his weight on it, but he's in that spot, on his own chair, that's placed on top of it, right in the middle. It's a matter thing. It's a physics thing. His chair is right there as well, and they're sort of occupying the same space."
Okay, at that point I always wonder: Where does Harvey's own chair stand on? Is there another Earth?
And that raises more questions:
How does Courtney see both chairs at the same time? How can he tell them apart? Is one chair transparent, or glowing, or something?
If there's a second Earth – let's call it another dimension because people are used to that term – does Courtney see it all the time? For example, are there trees that don't exist in our dimension, and Courtney can see them while walking around?
In the Reality of Harvey project, Intysam saw a pyramid near the water. Is that pyramid really there? Or is it part of Harvey's dimension, part of the second Earth that we can't see?
To be more clear about what I mean: In the Zelda computer games, there's this concept of the Dark World, or Shadow World. You go through a portal and are in a different world that looks very similar, but is not exactly the same.
Is it something like this? It must be when Harvey has his own chair.
And is that the reason why Yeme says in the Reality of Harvey project that it looks like two different moments in time?
And how many Earth's are there? How do we "tune in" to see the correct one?
And how do we distinguish between a reality and a projection?
If we're using Legend of Zelda logic then I would see it as Courtney having developed his 3rd eye to to be on par with the lens of truth item. The lens of truth is used in-game to see hidden walls, treasure chests, enemies, etc.
The portals to Dark World are more akin to CERN / stargates.
