No; the incident in question happened but once, and to my knowledge no one obtained their Persona in this way. Given that I chose to focus on investigating the hotel rather than that one-time lunar event, however, it is possible that this event was the necessary stressor for someone and I simply didn't hear of it.

Typically, one's Persona awakens in a life-or-death situation or other highly stressful circumstance. In my own case, Forneus awakened in the midst of a heated philosophical argument.
