Dear friend @brisby , you read mine 8 times and I read yours 4. It's a couple of days that I stare at your comment and move around it with cautious steps ..I even thought about it when I was driving to work.
I have to say this: first of all you cannot catch the idea because it's not made to be caught. Nowhere when I write (not the free - funny ones but "describe green", "metallic kisses") there's rarely the idea of a full plot. Even because it would be too structured for a freewrite. These are just bricks of a wider plan. Like amino-acids that eventually will compose a DNA helix one day... However, having said this, I'm glad that it resonated with your mind and ignited a creative process in you, since you had the feeling of giving to this little flash a wider context and possible interpretations.
Honestly I should not say anything, I wrote even too much of my ideas in this blog and usually someone - whether his ideas are good or not - feels like keeping them for himself when he's planning a book. On the other hand, writing like this has the benefit of unleashing the creativity..so I accept the trade-off between publishing ideas and at the same time make other ones flourish through this process.
If I really have to say something, the dream is taken from the Aboriginal of Australia culture. The dream for them is creation, it is real. That's why "lucid dream". This is a whole metaphor as Yoh's conscience and Yoh itself are split. Not for nothing, the first sleeps and the second ravages the earth, separated from its conscience. Aaaaand that's all folks! So basically this small piece is not simple at all and has quite a good bunch of philosophy (to be/ to exhist / to happen) and mystic doctrines. All of them of course can be developed a lot deeper and deeper. But i'd like to maintain a sci-fi realistic frame. Grazie grazie grazie for you always encouraging and deep thoughtful comments :-)
