Nightmares

In which nightmares become reality, Buffy loses her humanity, Willow loses her cool, Giles loses his perspicactiy, and Xander loses his clothes. (Exhibit B in the 'Xander is Hot' debate)

Official back-of-box synopsis:

When everyone's nightmares become reality, Buffy has to draw on her mental strength to put their terrible dreams to bed.

From the old WB Buffy website:

NIGHTMARE AT SUNNYDALE HIGH - The world of nightmares and reality become one when everyone in Sunnydale is living out their worst fears. While Xander comes to school in his underwear and Giles is unable to read, Buffy must unravel the mystery before reality folds completely into the world of nightmares.
