Dr. Ron Scolastico left a large body of channeled material from his Guides relating to this subject. Here is one directly relevant quote, from https://www.ronscolastico.com/a-thumbnail-sketch-of-life-and-death.html. It seems to corroborate your NDE experience at least to a small extent. For me, to the extent that this can be humanly understood, it still amounts to a great loss of human individuality, that is, loss of the human sense of self as the unique human personality identifying with the unique memories of physical life from early childhood, and identifying with the unique physical body. This is replaced by a vastly expanded form of consciousness with an entirely different basic "personality" (if you could call it that), manifoldly different memories, and with basically different likes, dislikes, emotions, etc. etc. The former human self becomes merely a sort of set of static "meta-memories" tucked into some cranny of the total soul being, which appears to be alien to the former human self. This picture may very well be the truth, but it is not surprising that few human beings would welcome this. From the strictly human standpoint it certainly doesn't look like "survival" in any meaningful form. It's interesting that some spiritual traditions claim that the human individuality is never lost. The Bahai Faith is one. Of course, there are other difficulties here: for instance their teachings also deny that there is any form of reincarnation, despite the overwhelming evidence from childrens' past life memories.
