I think letting your emotional inhibitions go away to temporarily clear out you stress is what happened there.
That is certainty one way of looking at it. I'm rather more inclined to think of it as emotional force myself. Powerful or strongly felt emotions create a palatable force to them that will effect the people who are the brunt of it. For example, think of when you were little and your parents were yelling at you, and how it was hard to speak or even think. Perhaps you where like me and cringed at every shout.
Ethereal Sight's seems to have felt something similar, a mass outpouring of empathy, that effected everyone there. Drum circles, mosh pits, synergy in a meeting, even religious serves can have the same emotional force to them. Enter a synagogue during yom kippur and try not to be solemn.
