The question you raise -- concerning the 'reality' quotient we can attribute to our interpretations of reality -- applies not just to altered states assisted by consumption of 'mind-altering drugs' but to all our interpretations of reality. And it comes down to the question of the kinds of information we receive through our own embodied consciousness and mind, with which our brains (in facilitating consciousness and mind) attempt to cope. My guess is that DMT, ayahuasca, and similarly mind-altering biochemical substances do 'open the doors of our perception' (in Aldous Huxley's phrase) to the extent that we receive additional information from the world with which our accustomed (ordinary, 'normal') brain processing cannot easily cope [i.e., sort, categorize, make sense of, interpret]. You've cited as examples "
very specific visual effects i.e. intense colour, geometric patterns, machine elves, grey aliens" and conceptualize the causes of these perceived 'unrealities' as "DMT accidental brain spill", "lone individuals concocting realities out of the hallucinatory realm", "just the entheogens talking." And that is what I want to question.
What is it that has led researchers and experiencers of the effects of these substances to propose that a different level of 'reality' is reached through their use? It's the commonality of their experiences, the apparent fact that they encounter the same things: more vivid colors, perhaps 'new colors', geometric (perhaps hypergeometric) phenomena, and the critters: machine elves, grey aliens, the mantis-like beings, and so forth. That users of these substances report seeing very similar 'things' naturally inclines them to think that they're seeing something 'real' that is 'out there in the world' since in our species' exploration of the local earth world we have generally been able to confirm a commonality of experiences. But not all of the experiencers conclude that they've visited an actual 'reality' additional to our own. @Ufocurious has told us several times that her current experimentation with ayahuasca is a form of research in which she hopes to find out how much of what she experiences through consuming ayahuasca is 'in her head' as opposed to being 'out there in the world', and I applaud her curiosity about this and her courage. She (and we) will benefit from whatever she (and similar critically minded experimenters) can learn from their experiences with ayahuasca (and by extension other mind-altering substances), a contribution to the larger effort to understand more about consciousness, mind, and the brain and how they work together in disclosing the nature of reality.
Anything's possible I suppose. That hypothesis might be easily tested by equipping people who claim repeated abductions with a home blood test kit which some might use soon enough to demonstrate the presence of DMT in their bloodstream. Hospitals cooperating in NDE research might also be persuaded to test the blood of patients flat-lining in ERs and surgeries for DMT for evaluation in cases of reported NDEs. These samplings could be extended far and wide in time, sufficient (if DMT is consistently found in most or all of them) to persuade materialists that these experiences and perhaps other anomalous experiences reported over millenia can be prosaically explained. Most people already prefer to think so, without evidence.
When I first read discussions of alien abduction experiences I thought that a) their consistency in details and emotional reactions required that they be investigated, and b) that it might be the case that this consistency resulted from common limitations in the human brain's capacity to make sense of whatever was actually going on. It might be, I speculated, that nothing more was going on than a vague, inchoate, sensing of an intrusion into the minds of 'abductees' rather than into their bodies and that they correctly sensed this much but, emotionally alarmed by it, interpreted it as similar to human medical procedures against which the embodied individual feels (and indeed is) helpless. Similarly, individuals claiming to have been taken for trips into space aboard ufos might have done so only in a virtual reality conveyed telepathically into the conscious and subconscious mind of the percipient. I still think that telepathic communications by entities other than ourselves is most likely to be the source of the above 'experiences'. For what purpose? To expand our thinking to take account of life beyond our own as narrowly experienced and interpreted on this planet, to prepare us gradually to enter a galactic or universal community of other intelligences, societies, and ways of living. Most of what we are uncomfortable with in various ufo phenomena might be merely the result of the native limitations of our brains [embodied and thus emotionally vulnerable] in making sense of
ideas and
representations of reality being expressed to us from beyond our accustomed 'world'. I think we need to work on anomalous phenomena with our
minds, exercised to the greatest degree possible
without presuppositions.
[Burnt continues, I interpolate comments]:
Still, I do leave the door open for the possibility of alien visitation in our skies
{I agree; there is tangible physical evidence of this} or some odd trickster element
{the trickster element is, I think, within ourselves, a figure we project outside ourselves but which originates in ourselves as a coping mechanism}, or even ultra or intraterrestrial
{that is of course possible} that create such incidents in the populous for reasons unknown
{do 'they' seek to confuse us, or do we respond to their incoming information with confusion of our own?}. But I do not think we will contact them with entheogens.
I think they have their value in society, but I don't think that's one of them. {I think we can use entheogens as a further pathway into understanding the workings of our own consciousness, mind, and brain.}
And now, for what it's worth, I think that ufology might be right when it comes to
lone individuals concocting realities out of the hallucinatory realm {that's unfortunately presuppositional thinking} that
instead of benefiting their inner development or bringing about healing, may in fact be emotionally charging themselves with completely unhealthy thoughts that can lead to a different gate after all. It looks to me like the evidence goes in the opposite direction, toward expanded consciousness, an appreciation of the interconnection of our species, other species, and our shared planetary ecology. I see nothing unhealthy in those ideas.
