How do you know you're real? Is existence all just a big dream? Has some mad scientist duped us into simply believing that we exist? James Zucker investigates all of these questions (and more) in this mind-boggling tribute to René Descartes's "Meditations on First Philosophy." \[Directed by Stretch Films, Inc., narrated by Addison Anderson\].
