Description : What is that reflex that causes some people to be violent in the first second after they're awakened unexpectedly?
Last Answer : I think it is normal to react when somebody wakes you up unexpectedly. In nature you should protect yourself from somebody who wanted to attack you and this is the way you are protecting yourself when you are not conscious. Does that happen when the alarm clock is ringing?
Description : What is that startle reflex that makes you jump or twitch awake?
Last Answer : I think you're referring to the hypnic jerk reflex. This happens during the transition from wakefulness to sleep, aka hypnagogia. Since the a typical night's sleep cycles through around four ... wakefulness, there are several such transitions. The hypnic jerk reflex seems to be related to stress.
