Flashing Lights In Eyes After Bright Light

Why We See The White Light Near Death

There are probably few experiences you couldhave that would confuse your brain more than almost dying. Hey friends, Laci Green here for DNews. quot;Neardeath experiencesquot; have been described by people across the world who cameor thoughtthey were comingwithin an inch of their life. What's totally crazy is that no matterwho you are, where you come fromeveryone describes it very similarly. It starts witha warmth spreading throughout their body, absolute serenity and calm, some might evencall it nirvana. Then comes a bright light and a feeling of being detached from the body,as if you were floating.

The number of people who have a near deathexperiences is on the rise, thanks to technologies that can save people at the last moment. Naturally,there's a burning question: WHAT DOES IT ALL MEAN!éé This is a complicated and emotionally chargedquestion. For some, the near death experience is proof of the afterlife. For others, it'sa fascinating neurological question. Let's take a look at this phenomenon through a scientificlens. One of the most highly regarded studies onNDEs comes from the University of Kentucky. They found that some Near Death Experiencesmay actually be something called REM intrusion.

During REM intrusion, the mind awakes beforethe body, which can trigger hallucinations. It's sort of like dreaming while you'reawake, kind of. I covered this phenomenon in my tutorial about sleep paralysis, so if you'reinterested you should definitely check that out cause it's freaky stuff. Because REM intrusion happens in the brainstem,it's possible for this to occur even when higher functioning parts of the brain havegone dead. Building on this research, trauma to the braincan result in a sensory mixup. As your brain struggles to stay alive, all of that chaosresults in an information overload in the

visual cortex. This is known to produce visionsof a bright light or a dark tunnel. The brain also releases a flood of happy endorphinswhich put you in a profound state of peace and calm. And because your brain is responsiblefor orienting your body relative to everything around you, trauma and oxygen deprivationcan cause a sort of out of body experience. This has been observed in lots of people whoaren't having a near death experience as well. Lastly, a new study has been published bythe Proceedings of the National Academy of Sciences on NDEs. The study was done on rats and found thatafter cardiac arrest, there is a crazy spike

in neural activity. The lead author says thatquot;if anything, the brain is much more active during the dying process than even the wakingstatequot;. Essentially, the neurons go into overdrive as death sets in, causing the brain to gohaywire in a predictable way cue warmth, bright light, floating, etc. We perceive thisexperience with profound intensity as our brain takes a last hurrah before death. I can't decide if this is beautiful or terrifyingor depressing or what.
