Darrin wonders if his life would be any different if Samantha were to tell the world that she is a witch. To purge such thoughts from her husband's head, Sam conjures up a nightmare for Darrin, wherein he discovers that too much knowledge about Sam's magical powers would result in nothing but grief for everyone concerned. By the end of the dream, both Sam and Darrin have been forced to join the army under threat of being burned at the stake. Written by Richard Baer, "I Confess" originally aired on April 4, 1968. ~ Hal Erickson, Rovi
