Dream is the only genre.

It occurred to me while watching Intimidation how all film, all art, is dream. Dream is the only genre.
Then I thought how realism and it's corollary, world-building, are anti-dream. In the same way that atheism is anti-religion. It seeks to oppose something by first redefining it as something that it isn't.
When I watch a film, or read a book and say dismissively, "That isn't plausible!" or "That would never happen in real life!", well, that's beside the point. I wouldn't say that about a dream. It's power doesn't lie in how close it is to reality.
The opposite of this is the modernist art-for-arts sake idea that we reveal the flatness of the painting's surface as an anti-realist, or anti-illusion, anti-mimetic technique. But this doesn't use the grammar of dream. It's not a dream language. The dream isn't entirely and only about the fact that it's not reality.
Surrealism sometimes gets close, but too often relies on stylistic techniques, e.g., placing random, unlikely objects next to each other. This happens in dream, but for a purpose.

Time wasted: it all contributes

"If I end up with just a few lines of dialogue, it no longer panics me. All time spent considering your play is well spent, regardless of outcome. One day you write nothing, the next you write eight pages. It’s not in your hands."
David Hare

I like this. I like this bit; All time spent considering your play is well spent, regardless of outcome.

He's not saying it's okay to not produce. He's saying, the important thing is to stay focused, or 'hovering over' the project. It's good because the focus isn't on productivity or being prolific, and he's kind-of shrugging his shoulders. This is just the way it is.
