It is called Mass Psychosis

the most prevalent psychogenic cause of a psychosis is a flood of negative emotions such as fear or anxiety that drives an individual into a state of panic.
This panic is painful.
Psychotic Break: a psychotic break is not a descent into a state of greater disorder as many believe BUT a reordering of one’s experiential world which blends fact and fiction or delusions and reality in a way that helps end the feelings of panic and fear.
