A few contrasting conclusions from a different websites and researchers.
From the Institute for Near Death Studies:
'People who are in a distressed frame of mind at the time of their near-death episode and those who were raised to expect distress during death may be more prone to distressing NDEs. People who attempt suicide are almost always in a distressed frame of mind. Usually they are attempting suicide because they feel themselves to be in unendurable and unending emotional or physical pain. In addition, they are almost certainly aware of the widely held belief that suicide is cowardly and/or the wrong way to escape the pain of life. Although they hope for relief from their pain, they may also consciously or unconsciously fear punishment. In a heightened state of pain, as well as of fear and/or guilt, they are highly distressed and, consequently, may be somewhat more prone to having a dNDE.'
From the Near Death website:
'In "Life At Death" I [Kenneth Ring] compared the NDEs of three categories of people who differed chiefly
in the circumstances that had brought them close to death: illness victims, accident victims, and suicide attempters. On the basis of my own findings, I then proposed what I called the invariance hypothesis to indicate how situations such as how one nearly dies affect the NDE. What the invariance hypothesis states is that there are no relationship: However one nearly dies, the NDE, if it occurs, is much the same.
Research published since "Life At Death" has tended to lend strong support to the invariance hypothesis. We now have cases on file of almost every mode of near-death circumstance that you can imagine: combat situations, attempted rape and murder, electrocution, near-drownings, hangings, etc., as well as a great range of strictly medical conditions - and none of these seems to influence the form and content of the NDE itself. Rather it appears that whatever the condition that brings a person close to death may be, once the NDE begins to unfold it is essentially invariant and has the form I have earlier indicated.
Subsequent research on suicide-related NDEs by Stephen Franklin and myself and by Bruce Greyson has also confirmed my earlier tentative findings that NDEs following suicide attempts, however induced, conform to the classic prototype.
In summary, so far at least, situations covering a wide range of near-death conditions appear to have a negligible effect on the experience.'
