Have any of you read The Fall of the House of Usher? (House of Usher) [img]images/smiles/icon_smile.gif[/img] These two stories are alike in innumerable ways. My interpretation of the House of Usher (for those of you that have read it) is that the House is not real. The narrorator is making all of this up, and symbolises his descent into madness.
This is what I think the House of Leaves is. Johnny's descent into insanity. The House represents his mind, hollow, ever changing, never ending, and extremely dark, and extremely not real.
(If you have read House of Usher, there is a description of a painting of a hallway that doesn't seem to end with faint light, veerrry similar.)
There is also a termonology in literature known as doubling. Like a mirror, Johnny seems to mirror a younger Zampano, Tom mirrors Navidson. They are twins, with exactly the opposite personalities. One, the rational thinker, and the other, the instinctual. Together, they create a normal human being.
What happens if you face mirrors at each other? There are endless reflections, they keep going and going and going, and you never see the end. I believe that every character mirrors some other character, but I can't tell you which right now, because I would have to go grab the book and study it again.
My theory is that Johnny is going insane, writing about it abstractly with the theme of mirroring, (doubling).
