A Jungian Analyser's Question - Is This a Past Life?

This is without LSD, this is through a breathing technique only. This Hindu process was very rapid and deep breathing. Eventually the ego would be less present in their field of consciousness. And then other aspects would become slipping in like a dream sequence. My question to you as a Jungian analyst is how do we know this is a past life? It may well be that the psyche has opened up so much that it's really tapping into the great universal mind. I think both of those things are possible.
