If you are not aware of what this is, DMT (N,N-Dimethyltryptamine) is a psychoactive compound that falls into the category of 'classic' psychedelic. This means that it's activity is focused on serotonin receptors, much like Psilocybin, LSD, and Mescaline (it's structure is only a few atoms different than Psilocybin).
The most striking thing that sets this apart from other psychedelics is that it is much more abundant in the biological ecosystem, and most importantly it is produced in the human body as a part of everyday metabolism (in smaller levels) and is believed to play a role in natural elevated states of consciousness such as dreaming, meditation, and near death phenomena (in higher levels). It is also believed that a high dose of DMT is released from reserve (the Pineal gland) near the time of death.
What intrigues me most is that when humans deliberately explore the DMT state (by extracting it from plant sources, then inhaling the vapor from heated crystals), the resulting experience presents themes of parallel realities, entity contact, and an unmistakable sense of one's consciousness leaving the physical body.
I encourage INTPs (especially) to explore this, because of our ability to perceive and analyze objectively while transcending cultural presumptions that would peg this chemical as merely a drug that makes you temporarily "hallucinate". The main factor that inclines me away from this (even as a skeptic and a man of logic is it's existence in many, many organisms including mammals) is it's presence in many organisms, which inclines me to believe that DMT related perception has some "real-world" validity and serves a biological purpose.
If you are intrigued by this and don't have the time to research it thoroughly, I suggested starting here:

There is also a longer (a little over an hour) and more thorough documentary that was released only a few months ago by an independent film maker:
I would be very interested in your thoughts on this, what you think it's purpose is, and what you think of the possibility of DMT allowing us to perceive a legitimate alternate reality that may be awaiting us after death.
