As promised, here is the link to Descartes' Meditations (a *.pdf document). Your mission is to read the First Meditation (about 2 and a half pages), in which Descartes asks the question, "Dude...what if reality really is a dream?"
As you read (by the way, it's pretty easy going), pay attention to the stages of Descartes' thought experiment. Why, exactly, does he reach his final decision at the end of the Meditation? What about God? Notice how the "Doubtful" character uses our everyday experiences of dreaming to make very strong skeptical claims.
