inside our brain, precisely where the pineal gland is located, dimethyltryptamine (DMT) is secreted;
DMT is a hallucinogenic psychotropic substance, one of the most powerful, obviously its presence in the brain is insignificant quantities, but enough to allow us to experience things such as dreams and NDEs (or post-mortem experiences);
in fact, during the REM phase the pineal gland releases a quantity of DMT which introduces us to the famous dream world, the same dynamic occurs once the pineal gland begins to decompose, to dissolve, that is, precisely, in situations in which involve NDEs, as it begins to decompose rapidly, immediately after cardiac arrest;
this perfectly explains why many people attest to having experienced analogies to the afterlife or supernatural vicissitudes, there are plenty of these testimonies, therefore scholars on the merits have begun to summarize them into categories, the most common are the following:
- the manifestation of a warm presence emanating peace ineffable for human language.
- the expulsion from one's body in an "ethereal" form and the examination of the lifeless body in the third person, until the end of resuscitation.
- the journey inside a tunnel, in which a white and faint light could be seen.
therefore, it is no coincidence that the statements relating to NDEs are mirror images of the experiences concerning the effects of DMT, since the latter causes circumstances in which one views one's own body as if we were an external observer or reconciliation with dead relatives, luminous tunnels or even divinatory encounters (see ayahuasca).
therefore, it can be deduced that:
(and this also explains why a Hindu would be inclined to experience a theophany of Shiva (so to speak) more than one of Jesus Christ, vice versa for a Christian; since hallucinations are determined depending on which brain it is subject to, and multiple and colorful socio-cultural contexts reside in the brain.)
