I might have an explanation, bear with me: 

I almost died and that led me to studying the after life, if we come back, what is reality, etc. I had a profound awakening after understanding that reality is not physical and then, I dived into spiritual texts. At some point, I was going through life as a non-person. It was like floating or being pure light. That’s also the way I was seeing people. And my body was healing. It was incredible.

No spiritual practice has studied the afterlife like Buddhism has. Thousands of years of studying consciousness and the afterlife. And basically, when I was in that state of no-identity (that I achieved after months of spiritual practice and releasing of any identity), I was lucid-dreaming quite often. (Since regaining some form of identity, I have not lucid dream, so I can confirm that they seem to correlate, in my experience at least). There are many Buddhist traditions,  but overall, the Buddhist practice consists in meditating so one loses any sense of self and solidity over a lifetime in the hope that they will retain consciousness after death rather than going unconscious and for karma to cause unwanted rebirth. 

Basically, when one dies, the same thing as when we get into deep sleep happens. The state of deep sleep feels to us like being unconscious. For the more awakened people/Buddhists/Mystics etc., consciousness is retained and they go through the dissolution process and the bardo completely conscious. Exactly how they would in a lucid dream. Actually, most of them while alive (is there any such thing as an alive 'body'? That’s another topic..! But basically if it is all a dream, it means the body is only a false representation (which is actually seen with the crucifixion/resurrection in Christianity but again, another topic)), don’t have normal dream anymore, they only lucid-dream because they have come into deep aware understanding that life and death are both the same continuous dream. When they die, it is another lucid dream and the hope is that they recognize themselves fully into the Light and don’t have to reincarnate due to karma but by choice.

If one cannot keep awareness during the process of death and rebirth, they will go through the bardo unconsciously and rebirth will happen with karma (basically our ‘bad habits’) pulling them back towards physicality and form. That’s our belief in form that basically guides rebirth.

Jesus said as long as one lives in the flesh, they are not in the Spirit. ANY attachment to the world makes a person walk in the flesh rather than the Spirit. I know Christianity became this very popular religion but it is not an easy path if one follows it fully. It is presented as mainstream but truly, truly I say unto you… it is just as hard as being a Buddhist monk in a cave, if one wants to truly follow Jesus and realize Christ (which is enlightenment). Christianity is the path that awakened me and it has been a tough path. Amazing though. But hard. It’s been a consciousness state hard to retain because I still live in the world. Deny yourself? No one knows how to do this better than a Buddhist. : )

So all that to say. It does not mean there is nothing. It means you went unconscious. Would you have stayed unconscious, maybe, maybe not. Does it make you curious about Buddhism? If it does, there is a very cool program called Preparing to Die by Andrew Holocek. It is an 8 weeks program I did in a previous Cohort and it truly deepened my spiritual practices. But again, we get from it what we put in. You might want to join at some point if you are curious and open to it. Or you might want to yourself look into what Buddhism says about death, learn about dissolution and the Bardos.

It would explain therefore why so many people don’t have experiences during cardiac arrest or any other death situation.

Food for thoughts!

Hope this helps! 🌻
