http://grimm.wikia.com/wiki/Zombie#Side_Effects "After a Grimm is treated, they will suffer from Post-Traumatic Zombification Disorder. It is characterized by infrequent, short, spontaneous episodes of suspended animation, accompanied by minimal heart rate and respiration. To another individual, the person will appear dead, except that he or she is not weakened or prevented from moving. These episodes tend to occur when the affected person holds their breath for a few seconds."
