The Nightmare

   2015    Medicine
A documentary-horror film exploring the phenomenon of 'Sleep Paralysis' through the eyes of eight very different people. These people often find themselves trapped between the sleeping and waking worlds, totally unable to move but aware of their surroundings while being subject to frequently disturbing sights and sounds. A strange element to these visions is that despite the fact that they know nothing of one another, many see similar ghostly 'shadow men.' This is one of many reasons many people insist this is more than just a sleep disorder". This documentary digs deep into not only the particulars of these eight people's uncanny experiences, but it also explores their search to understand what they've gone through and how it's changed their lives. Directed by Rodney Ascher, he chose to focus on sleep paralysis as it had happened to him in the past. The film's crew initially began approaching participants via message groups, videos and a half dozen books that had been written.

The Normans: Conquest

   2010    History
Professor Robert Bartlett explores the impact of the Norman conquest of Britain and Ireland. Bartlett shows how William the Conqueror imposed a new aristocracy, savagely cut down opposition and built scores of castles and cathedrals to intimidate and control. He also commissioned the Domesday Book, the greatest national survey of England that had ever been attempted. England adapted to its new masters and both the language and culture were transformed as the Normans and the English intermarried. Bartlett shows how the political and cultural landscape of Scotland, Wales and Ireland were also forged by the Normans and argues that the Normans created the blueprint for colonialism in the modern world.
