would anyone be so bold as to venture an opinion on the metaphors 'warehouse eyes' and 'arabian drums'? They're pretty obscure so I'm sure everyone understands them slightly differently.... I always thought of 'warehouse eyes' as sort of trying to contain what he sees, ie. sara (or whoever this song is addressed to) within himself. There's probably more to it than that though, and 'arabian drums' i just don't know.....anyone?
