Lyric discussion by walter91 

I think the title of the song refers to the unlimited possibilities life offers us hence life is a "room a thousand years wide". In this case, though, the songwriter deals with having been denied certain paths his life could have taken (because he did a mistake, something wrong or because something bad and unexpected happened).

1) "Listen, hear, he is inside One who lives while others lie I close my eyes and walk a thousand years A thousand years that aren't mine"

He still thinks about the time when he had certain expectations And his past self is still alive inside his mind He relies on his immagination to picture a future he could have lived but now he is unable to reach it

2) "It seems he's near me as I walk One who loved what love denied He lives these years that I walk blind All these years cannot be mine"

Same as above. Furthermore it seems love denied him other things he already loved so we can assume that the consequences of the love for something/someone is the cause of his dissatisfaction

3) "A thousand doors a thousand lies Rooms a thousand years wide He walks in the cold sun and wind All these years will not begin"

His past self is being finally taken away because he realizes that the years that he wished will not begin, because he will not live them and there is nothing he can do.

This song is quite close to me if my interpretation is correct: a disease I had some time ago prevented me from achieving certain life goals. I overcame that but sometimes is not so easy to quit thinking like "what if everything just didn't happen?". Great songwriting by Chris Cornell.

I think the lyrics were actually written by Kim Thayil, but it's a great song anyway, you're right
