"Is This The Real Life/Or Is This Just Fantasy"

One of the most instantly recognisable lyrics ever penned, Freddie Mercury questions what is real and what is not real. Yes, gentlemen, it's a bit of a philosophical one this time, so get your best metaphysical hat on and discuss reality, perception and the possibility that our surroundings may not be as they seem.

And no more references to 70's rock opera bands; one is quite enough already.

I won't impose a word limit, but the due date is 14 May 2006 give or take a few days.

Post scriptum: I know a couple of you have not had your say on war, but in order to end the current status quo of inactivity I thought it best to crack on.
