In the end I went for the "stirred up memories" interpretation. In early 2012 I spent four months on sick leave due to stress-related burnout, something which in many ways is the disease of our age (at least in the post-industrial economies).
This month, Odense Teater presents a performance (rather than a play in the traditional sense) with burnout as its theme. It was based on stories told by real sufferers of burnouts and then edited and dramatised by the writer and director of the performance.
Even if I got away from my burnout relatively easy (yes, I did write "four months of sick leave" above), the stories definitively stirred up memories. But then again, it is not so much people like me who should learn from the performance as leaders and managers continuing to push people over the edge.
