Well it would fall into the definition there, wouldn't it, is it only called a meltdown if you virtually lose control completely? if so i've had quite a few, but i usually just stand very very still, looking away from people and when i cross eyes with them in such a situation, they'll later tell me that i looked as if i was about to kill them with my gaze. If it doesn't get solved by just abstracting myself from reality, then i'll run away from the place completely and might hurt people who stand on the way...
