Why do I get goose bumps during scary movies ?

Goose bump are produced by piloerection, a reflex that contracts the muscles around the base of each hair follicle, causing the hair to stand up ( and small bumps to emerge ), says Zoe Draelos, M.D, a consulting professor of Dermatology at Duke University.
Back when humans were hairier, piloerection had two benefits: It helped keep us warm by trapping heated air close to the skin, and in scary situations, it made us look bigger and more threatening ( like a spooked cat puffing up its fur )
Watching a horror flick in an air-conditioned theater provides the perfect setup for piloerection: You're not only frightened, you're also probably freezing.
