I think it is about a person that gives in to temptation easily ("big monster lover," "bigger pusher over"), and consequentially remains lonely ("stands/walks alone...") and often times in a psychedelic state of mind ("see you looking through me," "saw the back of your sweet mother's head / now I know that she think's I'm dead"). Ultimately, this person will die and realize how poor of a choice it was to give in so easily to temptation ("can't you see that we're going to hell?").
