How familiar are you with NDE and what are you curious to know about them?  NDE is Near death experience.
I'm not very familiar with NDE or Near death experience. My husband almost died in a truck accident but I have never personally experienced one.
Sorry to hear about your husband.  Glad he survived.  Hopefully I'm not intruding asking about this, but did you husband experience a NDE?  It can include feeling a detachment from your body,  levitation, warmth, security, the precense of light.
