We know that when people are dreaming or hallucination the EEG shows activity in certain parts of the brain so we can rule out that during the flat line period there are any. The observable fact is, no activity, no dreams, no hallucinations. How do we explain the NDE in that case:
1-your awareness, which, as neuro research has established has left and is transferred to a spiritual dimension where it is restored without the necessity of brain chemicals and electronic action. Whatever you experience in this time, upon the restoration of the brain function, is then transferred back from the spiritual world, and imprinted in your memory cells, so you can relate what you saw and heard in the spiritual world, or
2- No awareness, no dreams, just nothing is transmitted to your memories, just a blank period, upon restoration you get access to your memory again but it is confused and pieces together old memories, creating new ones by confabulation, dreams and hallucination, to make sense.
Taking into account that the existence of a spiritual plane is a speculation, while the forming of memories by confabulation, filling in the blank in old memories, false memories, dreams and hallucinations are clinically tested, which explanation does have more credibility.
If number 1 was correct the anecdotal testimonies should give a similar picture of “heaven” but these testimonies vary greatly, depending on the culture or religion you were brought up in. Some report seeing Allah, Jesus, Buddha, Catholics see Mary, Protestants don’t. Many see their forefathers or other relatives. Number 2 NDEs are experienced by many people, including Atheists and they do all resemble the mixed up memory pieces of their previous lives.
“Confabulation is a memory disturbance, the production of fabricated, distorted or misinterpreted memories about oneself or the world, without the conscious intention to deceive. Individuals who confabulate present incorrect memories ranging from subtle alterations to bizarre fabrications and are generally very confident about their recollections” (Wikipedia, Ralph Underwager, Elizabeth Loftus, Richard Ofshe).
False memory syndrome (FMS) describes a condition in which a person’s identity and relationships are affected by memories that are factually incorrect but that they strongly believe ( Peter J. Freyd, False Memory Syndrome foundation –FMSF)
Now it is up to you to decide. Which explanation sounds more plausible?
