Lyric discussion by LiberatingFrance 

gunna have to agree with idleDreamer. its prolly most likely about drugs, and id suggest heroin. only reason is because seeing as its hard to sleep on heroin. also he mentions : "and there's a big black train coming d'you think it would be a shame running go into bathroom no-one looking anyway" people call syringes trains, and he mentions going into a bathroom and that no ones looking. the final suggestion to why its a song prolly about heroin is i have heard that the song "there she goes" is about heroin

@LiberatingFrance it is? I've never tried it, so I wouldn't know...
