ok, i have a theory here how this could work, based on a coulpe of other theories togheter.
The snare theory: every smallest particle (electrons, quarks...) are snares of energy who vibrate with a constant harmonious vibration, with their specific amplitude and frequency to be the different parts, together, they make atoms, atoms make molecules, they get together in structures and so on, you know this.
now: give every snare a certain level of intelligence, very limited, very primitive, just the pattern it should vibrate in to be what it is. Now say there are different types of snares, with the only difference in the strength of idividuality, meaning, that you can have leader snares, which dictate the pattern to the weaker snares. so you would get one leader snare in an atom, who uses the different snares who make up the parts of the atom, to gain more complextiy and the ability to grasp the whole idea of the atom and hold it together. then again there is a molecule-leader snare which holds all the atoms leaders in position. and so on. A human being so would consist of one snare being you, and if it were alone it only had the very idea of you, but with its body, and all the weaker snares you hold together, you get a much complexer network, allowing you to obtain thoughts, memories ideas and so on. because the you snare is strong enough to hold all the others togheter, you can exist. (a stone would be a stone and remain a stone because their is no way yet you can communicate it to him to be anything else, if you could give it another structure idea, and it'd be strong enough to maintain it, you could change the stone...)
and we go on: where do these snares come from ? therefore we go backt to the snare theory again, which predicts that snares would introduce more dimmentions.
so i say, there's a dimmension, i'll call it "outside", which is not anywhere in the universe, it's just another dimmension. this dimmension having no end, contains all the snares that don't have a pattern, but they have their variaty in "strength". so when a baby is born (or made, i mean, it happens before the baby actually comes out
), the mother summons a snare strong enough to hold the idea of a human being can answer to this, since these snares in the "outside" only have their self, they have no complexity and only one desire, a pattern. So than, if the snare that comes to the new human being idea becomes the idea, it can start summoning other snares who don't neccesarily have to be that strong because they only need to fill in minor ideas.
if you follow this theory, you could also summon snares into existence if you had a powerfull enough idea to summon one up to the job (strong enough) and for that, to keep such a huge idea, you would need enough "memory to hold it" you would need more complexity. mayabe you could do that by linking your mind/the you snare, to other complex organisms (or even artificial, like a computernetwork).
I have parts of this combined theories from the book-series "Enders Game" by Orson scot Card ( I think it's the fourth book where they really discover the thorie, but the three foregoing books it allready starts...) They're good stories, exiting, so if intersted, here's an idea for getting a better view on this idea
