At the recent Academy of Neurology Congress, scholars reported that among 1,034 people recruited from 35 countries via an online crowdsourcing platform asked if they'd ever had an Near Death Experience, 289 answered 'yes.' When were asked for more details, using a 16 point questionnaire called the Greyson Near-Death Experience Scale, 106 reached a threshold of 7 on the Greyson NDE Scale. Some 55 percent perceived the their feeling as truly life-threatening.
Among respondents, 73 percent who claimed a near death experience said it was unpleasant, but those with a score of 7 or above on the Greyson NDE Scale had 53 percent pleasant descriptions of it.
