Stupor is a motionless, apathetic state in which one is oblivious or does not react to external stimuli. A sufferer is almost entirely unresponsive and only responds to base stimuli such as pain. Individuals in this state make little or no eye contact with others and may be mute and rigid. One might remain in one position for a long period of time, and then go directly to another position immediately after the first position. A person only appears to be conscious as the eyes are open and follow surrounding objects.
