Sacred Haven of Debauchery

I know what warp is, but even so, if we assume that warp doesn't exist, it's impossible.

and it doesn't necessarily have to be in his mind anymore

But the idea that our world is a kind of warp, a product of the thoughts of not one person, but many, many people – is a little more interesting. But still, not particularly.
In general, the most interesting theory is the officially scientific one. There is the Universe, and there are we. Or maybe there is someone else too. That's it (:
