I have wrestled with the possibility that witnessing a cryptid type of creature is purely internally generated by the witness, but I am left with the multiple witness accounts (as in more than one eyewitness at the same time).
My understanding is that the indigenous peoples have always maintained that Bigfoot is a "magic" creature.
I feel that information has been cherry picked or deliberately omitted in the hope of bolstering the "Bigfoot is a primate theory" including eyewitness testimony.
I could bore you to sleep by stating all the reasons Bigfoot cannot be a conventional animal, but as for saying what it actually is, I am at a loss.
But I think "it" is something not just a figment of peoples imaginations.
My best attempt to describe it would be that "emotion" can manifest itself (take on a "form/shape") to an extraordinary degree in the correct circumstances, but what these circumstances are, and the reasons they are triggered are as complex and varied as the experiences themselves. I think this all happens on a subconscious level but has a real effect on the conscious and the experience is real.
You don't have to look for very long for an example of "emotion" having very real effects on life.
Whilst I believe we Humans are the most advanced life form, I think we are a long way from understanding some very basic things about ourselves and how we operate, that said: we have made huge advancements in this area, and to my mind the evidence points to us being exceptionally emotional creatures, it is one of our greatest assets and one of our biggest vulnerabilities at the same time.
If the "God helmet"* is anything to go by, who knows what could be possible using the raw power of mother nature? (as in: huge unbridled electromagnetic or other naturally occurring forces) Maybe all you have to do is be in the right place (or the wrong place) at the right time and you are caught up in the gears of nature. Maybe people are hit by a wave of "energy" but not a "deliberately targeted one" that causes an extraordinary experience? this would go some way to explaining why such events can happen at any time in any place, be it in bed, in the woods or in the city center, driving your car, flying your plane, sailing your ship etc etc.
All this talk of "energy" seems a bit "woo woo" so to clarify I am not suggesting a new type of "magic" energy, just a combination of conventional "conditions" that result in an extraordinary experience.
