One for example, is conflict resolution from a past event. You had a conflict with someone, you feel treated unfairly etc.
This exercise lets you go back to that situation in memory, as yourself. Next step is to go back as an observer of yourself, looking at what you felt, etc. Then you are an observer of the whole thing. And finally, you go back as the other person, trying to understand why they acted like that, trying to understand how they felt.
After such a thing, a certain "wrong" situation can suddenly become way better, by understanding the other person and their drives. Understanding what other people feel, stepping in their shoes, can be very beneficial. Stepping "outside" of yourself and observing your feelings can also give a lot of insight.
So that was basically what I was referring to.
