Hi Brownie,
Actually I have studied NDE's quite a bit for many years and read many books about them. Request you to pl read Dr. Raymond Moody (one of the first researchers in the 1970's...'Life after Life') and Dr. Sam Parnia (very recent book...'What happens when we die?') besides others.
Pl check out the following if you want.
https://tsriramrao.wordpress.com/2012/01/19/near-death-expe/Most NDE's have very common features.
!. Floating above the body and seeing it from outside, Feeling of detachment from body.
2. Seeing and hearing activities associated with the body in the hospital or accident site.
3. Seeing dead relatives.
4. Moving through a spiral tunnel or staircase.
5. Seeing a bright light and a feeling of love and absolute knowledge.
6. Some people see others waiting for reincarnation (Christian NDE's not Hindus).
7. Born blind people are able to see like everyone.
8. Being told to go back.
9. Finding oneself being drawn back into the body.
10.Feeling a sense of heaviness and regret at coming back into the body.
11. Recalling conversations and activities in the hospital....corroborated by doctors and nurses.
12. Some people claim 'death is no big deal' and even look forward to dying again....though they feel a new sense of duty in this world.
There are literally millions of cases across the globe and people of all religions, races, nationality, cultures, sex and age groups have been studied for over 40 years. These experiences are certainly
not dreams or imagination.
Of course, there are some negative NDE's (about 20%) where the person feels fear and distress. There are also some different interpretations of who the Bright Light is. Some say Jesus ...some say Ram ...or Krishna ...or whatever.
It is also possible that there are some cases with very different experiences from the norm.....but a majority of the cases have the above pattern.
Most of us will naturally view these cases in the light of our own beliefs and comfort levels. Some people say..'they are all the same..so they cannot be real experiences...they must be brain generated visions'. Some others say...' they are all so different ..so they cannot be real experiences...they must be dreams or hallucinations'.
So...it is a mystery ...but some doctors like Sam Parnia and many others are still studying the cases. Unlikely that they will be able to offer final and conclusive reports on them.
To me, they are real Out of Body experiences and real After Death Experiences (Sam Parnia has specifically mentioned that) and not Near Death Experiences. They do offer us a glimpse of what lies ahead for us after death.
Cheers.
Sriram
