Aura
An aura is the field of light some people report around living things — colours that change with mood or health. Neurology owns one solid piece of the topic: migraine and epileptic auras genuinely paint halos and shimmer around objects, and synesthesia can colour people reliably. Energy-field readings beyond that have not survived testing. The archive keeps aura stories for their specifics: the hospice worker who learned one particular dimming too well, the child who asked why grandpa's light was leaving a week before anyone knew he was ill.
