The 4th Wall

I feel like I should provide my own analysis to Nabokov's Symbols and Signs, if for no other reason than that it's very enigmatic, and the more angles we approach it from, the better.
So when I started reading it, I didn't really know what to expect. I knew what it was supposed to be about, but not the way in which it would be presented. I noticed that there were a lot of red-herring type of things in the story, which was to be expected, given its nature. What I determined then, was that the meaning probably had something to do with what was not being told to us, more so than what was. This makes analysis pretty difficult, since there are a lot of things not being told to us, but there are few things that are not so much addressed, but that may still be reasonably inferred. What I came up with was this:
The boy might have been right. The trees might have been whispering about him, and the thunder clouds far far away from his immediate sphere of consciousness might have been rolling out plots against him, and the whole world might have been out to get him if for no other reason than that it was his story. Everything in the story WAS about the boy in one way or another, so how was he supposed to escape that? He was just hearing all of the coughs in the proverbial audience, which no humans are supposed to hear, since to us there should be no audience, right? in other words, that fourth wall that actors are never supposed to break, don't look at the camera and all, that boundary has been recognized by the character in this story. Ironically it is supposed that the boy has a mental disease because, to the other members of the story, the character is not a character, he is a real person. So really the character who is crazy, is actually the boy who knows too much, and he is trying to tear a hole in his reality, so that he may join us in this one, which in a metaphorical way he has done, since we've all spent time thinking about him. The other idea posed, then, is that we may very well just be the characters like everyone else in the story, simply ignorant of the fact that the fourth wall exists. (This, of course, is a metaphor not to be taken literally. Please do not try to fly out of this reality and hurt yourself) And what better way to defeat a wall than to go over it? what better way to transcend the version of reality that we see, what greater freedom is there, than to fly?
