@Soupie thanks so much for posting about the default brain mode as increasingly it is cropping up as an area to place much more emphasis on. What's curious about the psychedelic experience is that following the smashing of the ego - sometimes a difficult entry without a cushion - there is a new mode of reality. Everything is new, tactile, intensely visual like your senses are suddenly wild. I can also see how the reptilian brain gets activated as the 'startle capacity' is on high alert. For fear junkies, you don't really know what being scared is until you've been scared on acid. The sudden shifts and alterations of external reality may indeed be crawling up from deep in the mind's resevoirs, but the experiencer does not have any awareness of this whatsoever. I can see how when the doors are wide open, anything can jump out.
These are journey experiences, and like any significant journey the imprinting on the individual is very intense. Elsewhere on the forum we have described dreams, and right now there is a thread asking about your most powerful dream. That images can have such a profound effect on us, even moreso when accompanied with the right neurochemistry, is fascinating. How can you not share such things with the rest of the tribe? I don't believe that our dreams are commonly interpretable, or that dream symbols are open to being categorized. However, our own dream imagery can have exceptional individual meaning. In some cases they mean so much to us that the images become unforgettable.
When ego dissipates, one can't help but wonder how startling our own mind can be when it is allowed to manufacture its own random imagery. I can still remember a very intense childhood dream of my father defending our family from a male and female Bigfoot who had broken into the home. It was maddening. But it can only hold the meaning that I choose to give it, and just as easily I can surrender to the power of such images and let them occupy my daytime concerns. This may in turn lead to other problems of my own unknown manufacturing.
I wonder if there's general agreement yet among neuroscientists concerning the nature of the 'default brain mode'. This is something we might want to explore, and
@Soupie should probably be our guide. I first saw a reference to the 'default mode' or 'default network' about two years ago in an article in which it was described as a kind 'offline' state of inattention to present tasks, circumstances, etc., to which humans typically revert often while awake, entering states more like daydreaming, reverie, etc.
I'm not sure that it's the same state that leads to experiences by people having or dreaming about 'abductions' or having close encounters with a ufo and/or strange occupants of ufos in the vicinity of a landed ufo. Over the years I've read many of the latter type of accounts and am not remembering descriptions of the kind of terrorizing entities Burnt seems to be referring to. But I haven't read everything that Burnt has read concerning events described by John Keel; in fact, I haven't read Keel at all.
Anyway, I do wonder what the source is of genuinely terrorizing images of entities that I gather are encountered by some users of 'mind-altering' drugs such as LSD and Ayahuasca, and also why it seems that many DMT experimenters are reported to encounter certain specific types of entities (insectoid ones as well as cartoon-like characters). It does seem to me that these apparently powerful substances must be significantly responsible for the types of human experiences that result, and that these experiences are significantly different from, e.g., NDE's and deep meditative states, which
@Soupie included in his speculations.
I think that to understand all this better we need to sort out/make some distinctions among different types of experiences of altered consciousness rather than assuming that they all have a common cause. And I think we also need to be aware of the limitations of current neuroscience in understanding the subconscious mind and what it contains.
In general I found myself in agreement with
@LatentCauses post earlier in this thread (linked below), from which I extract this paragraph:
". . . the reason that we feel as though the witnesses describe non sequiturs, is because their senses are overwhelmed with far too much information, and information in a form that our pattern recognition processes have never seen before. At this juncture you can throw in a pinch of Jung and say that when confronted with this information, our brain scrambles around for the closest analogy, and drags bits and pieces from popular culture, mythology, our fantasies [insert whatever you like here...] and mixes that with its best approximation of what is actually there. Hence the persistent confusion and bizarre nature as to what is reported."
There are other ideas we can pursue in the rest of that post, at this link:

I think it's reasonable to say that both mind-altering drugs and shocking, disorienting experiences such as ufo/alien encounters clearly disable an individual's sense of what is normal and 'real', a sense developed over years of ordinary experience in our typical surroundings [a world taken for granted]. In fact that ordinary sense of reality is suddenly
displaced, and one result is a deep sense of fear, of incapacity to cope with what is encountered. Our 'fight or flight' responses, originating deep in the primitive hind brain, are summoned into action in such experiences. It might well be that this sense of danger, of fear or panic, is itself sufficient to trigger a grasping for explanations, and that the brain/mind seeks and finds some possible explanations or images stored in personal subconscious memory or in our species' collective unconscious. Any of these 'memories' might be more or less sourced in real experiences (our own or those of our predecessors) or alternatively sourced in overwhelming feelings we've had while watching horror movies or reading Grimm's fairy tales as young children.
