Nightmare

A man wakes up screaming, and his wife asks "what's wrong? Nightmare?" The man nods. "What was it?" asked the mans wife. He takes a second to wipe the sweat off his face before telling the story. "It was a wonderful summer day. We were all in the car going on vacation." "That doesn't seem too bad..." says the wife. "Then I realized that you were driving," says the husband.
