Franklin Delano Roosevelt, who gave thirty so-called fireside chats over twelve years, was afraid of fire and refused to lock his door while sleeping so as to ensure easy escape, which he would often practice by dropping quickly from his bed or chair and crawling to the exit.

Eighth-century Persian scholar Ibn al-Muqaffa recorded a parable describing human existence. A man, fearing an elephant, dangles himself into a pit to hide but soon realizes a dragon waits at the bottom and rats are gnawing at the branches he’s holding on to. He then notices a beehive, tastes its honey, and becomes “diverted, unaware, preoccupied with that sweetness.” While he’s distracted, the rats finish gnawing the branches, and the man falls into the dragon’s mouth.

Greek geographer Strabo wrote around 20 BC that, to deal with “a crowd of women” or “any promiscuous mob,” one cannot use reason but rather must exert control using myths and marvels. “For thunderbolt, aegis, trident, torches, snakes, thyrsus lances—arms of the gods—are myths,” he wrote. “The founders of states gave their sanction to these things as bugbears wherewith to scare the simpleminded.”

A surgeon in the British navy published an 1816 treatise on “The Incubus, or Nightmare, Disturbed Sleep, Terrific Dreams, and Nocturnal Visions,” arguing against folk beliefs that nightmares resulted from overindulgence and sleeping on one’s back. Sufferers “can bear testimony to the distress and alarm,” he wrote, “in many cases rendering the approach of night a cause of terror, and life itself miserable.”

A hen near Leeds, England, caused a panic in 1806 when she began laying eggs inscribed with the words Christ is Coming. Terror of Judgment Day swept the population until it was observed that the hen’s owner, Mary Bateman, who had been charging a penny per visitor, was writing the message on eggs and forcibly reinserting them into the hen to be laid again.
