My only brother, an Army lifer, had one after a near fatal car accident in the DC area, 80s-90s? (He never even told us he had the accident, until years later). Gene passed in 2003, and his widow told me of it two years ago, said after that he was never afraid to die. Yeah, floating above the operating table, white light, etc., all that. I think Mom had similar in the 1930s during an operation.....she talked (very little) about similar issues. I think totally misunderstood back then...attributed to hallucinating, maybe? Never heard of it while growing up.
My most dangerous? Maybe the parachute jump into the Pisgah Mountains, Western NC, end of the Green Beret training, August, 1965. Never considered it near death.....found myself standing on top of an A-Team Sgt"s chute, about 800 feet off the ground. Airborne training kicks in INSTANTLY!!!....YOU WERE taught you have 3-4 seconds to decide which way you"re gonna walk off before your chute collapses. Sure, you can ride HIS down, but you die cuz you"re 30 feet off the ground when he lands. BTDT! Better half and six kids could verify!
