I know someone who had a similar event happen in training, except the deep and dark secrets were meant to be shared among a group of six or seven. People shared actual deep and dark secrets; crying was involved. My friend who told me about this was deeply uncomfortable with the whole affair and found it bizarre and cultish, but of course, they went along with it and made up some semi-plausible thing to be a "team player." Amusingly enough, IIRC, it was also a phobia.
I wonder if phobias are just easier to share because some of the more common ones most of us share are ones we know are probably not very rational but still powerfully held.
