I like the idea, it sort of reminds me of the saying "See no evil hear no evil speak no evil". However I don't see the connection between the first and second lines in the second stanzas? Some people would argue that having no light would allow for MORE time to think, so maybe for the second line, try something to the effect of "my mind is cluttered with crap". But obviously better vocabulary.
Similar jist with the first stanza, maybe it's hard to stand when the world keeps spinning or something like that. But it's poetry so it's really relative to the readers and absolute only to the author.
