First time I watched my life flash in front of my eyes but like a movie. I could see everything/memories I had forgotten. Felt like I watched myself be born all the way to the moment I overdosed. Then I saw these blue beings. They were made of... light I guess. They looked like birds. They were telepathically communicating with me telling me everything was okay and that I had been in amnesia and had chose to live this life but forgot. They told me everything was going to be okay but that I wasen't supposed to be there or see them. It was the greatest feeling ever. I remember feeling so much love and protection. They told me "you have to go back now" and I woke up to somebody saving my life. I guess they did cpr or something im not sure. Years later I googled and researched "blue bird like beings" and a bunch of information came up about "Blue Avians" and "Beings from Sirius" idk what any of it means but yeah that was my first NDE experience. Last time I overdosed which was in 2020 on heroine I didn't have an experience like that again it was just black.
It doesn't sound like you were actually dead. When the brain is starved for oxygen and goes into a state of hypoxia, it starts to produce it's own DMT.
Scientists recently discovered an enzyme that changes the common amine tryptamine into DMT. Indolethylamine-n-methyltransferase (INMT) is an enzyme found in the body that converts tryptamine to DMT. Research has also shown that a specific receptor called the Sigma 1 Receptor plays a protective role in hypoxia, and that DMT is one of the few endogenous amines that binds to this receptor.
Replicating the stress neurons undergo with a lack of oxygen and testing the effect DMT has on the neurons under these conditions, results showed that DMT robustly increases the survival of these cell types in severe hypoxia.
In other studies rats showed surges in the levels of DMT in their brains when they experienced cardiac arrest, which was induced by the researchers as part of the experiment. Crucially, this happened even in rats whose pineal gland had been removed.
This further suggests producing DMT is the body's way of trying to regulate neural signalling and brain/peripheral immunological processes (Shen et.al., 2010; Frecska et al., 2013; Szabo et al. 2014)
I'd suggest that you were not actually having a near death experience, you were just tripping out on dmt.
Most people claiming to have had a "near death experience" are no where near death, when they had the experience. There is almost always an alternate explanation for why they report having such an experience, perhaps they were given ketamine by the doctor, or perhaps their brain/body was entering hypoxia and began producing heightened levels of DMT at the time. I don't think such experiences are evidence of an afterlife, or that humans have a soul, or that those people actually left their bodies and were having out of body experiences, etc.
Whenever I have heard from someone who has actually died, they always report experiencing nothing:
I was dead for a short period of time. There is nothing there
This is pretty much what I have heard from anyone who has clinically died and were revived in a hospital or clinal setting. They report having no memory, no awareness, no consciousness of anything.
As stated above, I think there may be certain conditions under which your brain may produce or release endogenous dmt when a person is close to death, but not everyone will experience it. I think you are more likely to experience it if you are slowly bleeding out, or suffocating, and you are aware while your brain enters into a state of hypoxia. If you lose consciousness fairly quickly, or if the brain is sufficiently damaged so that consciousness is impaired/suppressed, I think you might not experience much of anything.
If true, then it represents your brain/body's last ditch effort at trying to preserve the cells. There is nothing spiritual or significant about it. I think this is probably another one of nature's cruel jokes, there you are dying and your body produces a bunch of DMT and you start tripping out. Some people report feeling peaceful, calm, seeing a light, but I think for me it would probably be a bad trip. I hope when I die I am completely knocked out so that I don't experience anything like that.
