Its activation of the sympathetic nervous system. It primes your body for action; it's the method of action for the flight or fight response. Controls breathing, heart rate, blood pressure, pupil dilatiion, sweating and other things. Right when its activated it causes all your muscles to contract and your body to freeze, that is the source of the feeling.
