Psychological explanation


dissociation



depersonalization



reactivation of the memories of the birth



regression



a sort of « dream »
mental representation of the situation and the scene

THE MIND-BRAIN DIVIDE


phenomena that current scientific knowledge can’t explain
the “veridical perception”

At the wake up, some patients reports of apparently
unknowable facts that reprensent reality.

Is it possible that consciousness might survive the
decease of the physical body ?

PSYCHOLOGICAL OUTCOMES OF NDE
positive transformational outcomes


change in beliefs, attitudes or values



reduced fear of death



being kinder to others



being more motivated



and with positive effect on their response to stress

CONCLUSION
• human response to danger
• numerous cognitive, affective or paranormal elements
• no underlying causative condition is known
Existence of NDEs raises the questions :
Do the soul or consciousness dead with the body
Life after death ?
