I don't know if this will help shed any light on anything at all, but since Pros and Cons is a dream, we might wonder how much control the character has over the imagery of the dream.

What I envision happening during this song is that the character has had a false awakening. Perhaps he woke up halfway very briefly, and went back into a dream--but since he has just been awake, there are elements of the waking world in it. He sees himself in his room, but there are unfamiliar elements--i.e. the "Arabs with knives." I have had false awakenings myself, and usually there is some sort of disturbing element when I realise that things are not as they should be (for example, one dream where I began to float to the ceiling and was nearly shredded by my ceiling fan--or so the dream went).

As for Mr. Waters' selection of what elements to put in the dream, perhaps it could've been better, but I doubt very much that it was intentionally meant as an insult against Arabs. Again I ask (and I think a discussion on this would be interesting both in light of the "Arabs" issue and also apart from it), how much control does this character have over the imagery of his dreams?
