Dreamland is the sixth episode of the sixth season. It was released on 30 October 2009.
The team investigates an apparently inexplicable death by some kind of electricity at a decommissioned airbase, finding themselves teamed with an offbeat character from the Pentagon's elusive, even unheard of, Department 44. Elsewhere, David ponders his future and Alan celebrates a birthday.
This was "the Scooby Doo episode", with numerous references, comments, character quirks and story elements paying homage to the classic cartoon series, including the red herring 'government bad guy'.
