Different things get thrown into this basket in the Ortho-Bionomy world. A lot of instructors like to say it is a "mood." I'm not sure they really know what they mean by "mood" but they seem to have some specific mood in mind. I should write some in here about how mood is thought to bias cognition and when one's mood changes perception changes. Maybe further down more about mood.
The big shift of perspective that was introduced here has to do (perhaps) with empathy. It is a changing of roles. I could say Phase 5 is the lens of the carnivalesque (must make sure this is in the glossary along with reference to Bakhtin). The ruler becomes the follower and vice versa. The sublime and the grotesque bounce back and forth.
Phase 5 (we are often told) can be seductive. You may become enraptured in this mood. We are warned to resist that.
Phase 5 is much about haptics and non-conscious movement.
