Simulacra and Simulations

OK, this reading was probably the most confusing article we have read so far. I was very, very lost and I didn't think that anything really tied together from beginning to end. Jean Baudrillard begins by talking about simulations and the definition of simulation. "The real is produced from miniaturized units, from matrices, memory banks and command models - and with these it can be reproduced an indefinite number of times. It no longer has to be rational, since it is no longer measured against some ideal or negative instance. It is nothing more than operational. In fact, since it is no longer enveloped by an imaginary, it is no longer real at all. It is a hyperreal: the product of an irradiating synthesis of combinatory models in a hyperspace without atmosphere."

Then, Baudrillard explains dissimulation and simulations as having either "presence or absence," and with that babbles about dreaming. Am I missing something hear? I mean, seriously, who is his audience because I couldn't understand where he was going with that at all.

Shortly after, he describes Disneyland-which he explains, "the imaginary is neither true of false"- and the Watergate scandal-"an imaginary effect concealing that reality no more exists
outside than inside the bounds of the artificial perimeter." So, so far we have an outlandish definition of simulations and dreaming, and Disneyland and Watergate, which are real but not?

And how does communism tie into all of this?

Maybe I'm just not apt to reading material like this and it all, in fact, makes sense but I don't think I'm going to be reading and Jean Baudrillard for the hell of it.

In the final section of this article, he concludes by writing, "This is ultimately why power is so in accord with ideological discourses and discourses on ideology, for these are all discourses of truth- always good, even and especially if they are revolutionary, to counter the mortal blows of simulation." And after this, I still have to ask, so, this makes the Disneyland parking lot and concentration camps similar? I just don't see it.
