More importantly, the description isn't just found in trip reports. It's found throughout history, in reports of people who have had what are called peak experiences, sometimes involving trauma. There are many stories of prisoners in the literature, for example, who come to the realization that both the jailer and the jailed are the same.
Jack Kornfield is one of many who is famous for relating the story about how the person being tortured suddenly observes that the person torturing them is the same entity. I believe there are also many reports from concentration camps coming to the same conclusion. It's difficult for us to admit this, because normal waking consciousness would have us sort things into us and them, but there is a level of perception that one can reach, where the interconnectedness of all things is seen.
Many people tend to toss these things into religion or spirituality, but there's nothing supernatural about it at all, it's a biological and ecological reality. The question, however, that doesn't go away, is why are these peak experiences trying to communicate the same or similar ultimate truths to us, truths that seem to contradict and oppose the conditioning and programming of our dominant culture, which tells us we are separate from each other and should be fearful, aggressive, and violent.
