“Suspicions about us grew out of control now and then down through the ages, and we had to run or fight, or we were tortured and murdered as demons or as possessors of valuable secrets. Sometimes they hacked at us until they thought we were dead, then buried us. When we healed, we came out of our graves confused, mad with hunger … perhaps simply mad. Well, that’s how in some cultures we became the ‘walking dead’ or the ‘undead.’ That’s why they learned to burn or behead us.”
