Malaysia School Zombie-Like Rage (2001)

In a bizarre incident at Puchong Perdana National School in Malaysia in 2001, 30 girls suddenly exhibited a zombie-like rage, with screaming and violence spreading rapidly among the 1,100 students during a Monday assembly. Panicked students seeking refuge in classrooms led to the temporary closure of the school. However, the episode was not caused by a virus or chemical; rather, it was attributed to the girls experiencing heavy stress and pent-up energy in a confined space, leading to a mass hysteria event.
