A nice article from Scientific American... Does not say anything reassuring about an after-life but is still fairly 'middle of the road'.

About one in 10 patients with cardiac arrest in a hospital setting undergoes such an episode. Thousands of survivors of these harrowing touch-and-go situations tell of leaving their damaged bodies behind and encountering a realm beyond everyday existence, unconstrained by the usual boundaries of space and time. These powerful, mystical experiences can lead to permanent transformation of their lives.
NDEs are not fancy flights of the imagination.
But NDEs are recalled with unusual intensity and lucidity over decades.
The results suggest that the NDEs were recalled with greater vividness and detail than either real or imagined situations were. In short, the NDEs were remembered as being “realer than real.”
Noticing patterns in what people would share about their near-death stories, these researchers turned a phenomenon once derided as confabulation or dismissed as feverish hallucination (deathbed visions of yore) into a field of empirical study.
Interestingly, NDEs are no more likely to occur in devout believers than in secular or nonpracticing subjects.
Why the mind should experience the struggle to sustain its operations in the face of loss of blood flow and oxygen as positive and blissful rather than as panic-inducing remains mysterious.
