it was serene, peaceful and I felt total acceptance.
That last part.., they all feel that. A few more seconds and that white light might have appeared. Maybe you were not there for long enough?
My missus also had one, and met someone dead (who had recently deceased).
'its not your time, you need to go back', they said. The accounts are strikingly similar.
There is definitely some weirdness that goes on and I would have liked to have experienced the white light of it. For me though, there is no usefulness in thinking about an afterlife, whilst still alive and find it better to take the position of fade to black.
