1) Jeff, I am not dismissing either phenomenon but stories of dematerialzation and bigfoot as ultraterrestrial stretches credulity as much as said Bigfoot being remote controlled. Mixing faeries and Gnomes together is like a Disney movie and that's what happens when disparate paranormal phenomenon are blended together without any real substantiation beyond witness testimony.
2) We haven't even proven the existence or identity of either but we're going to mix them? If there was veracity to those claims, and you know that even Bigfoot prints are subject to a lot of suspicion on their own, then i coud entertain the notion. Hoaxing of these prints is not a complicated matter - even producing dermal ridges is possible for the avid practitioner.
And as previously stated, I'm not dismissing the many reports, but agree there have been many reports and that's indicative of a great number of possibilities, 3) and remote controlled Bigfoot are last on my list. I think what's much more interesting is how witnessing of strange and intense events produces other attendant phenomenon in the minds of those witnesses - Dale Spaur being a good example of this. Was he the only one that saw Floyd subsequently - that's my understanding of the situation?
Getting us back to the thread, a lot of people are affected substantially and have their perceptions altered significantly for reasons unknown, entering the Oz effect, and as you previously commented on, a distortion of usual reality including shifts in sound, light, and a lack of other people even. Does this not sound like an entirely internal experience, with no real other confirmation? I contrast such cases with radar return, physical evidence and multiple witness events.
But those common sightings that are taking place across wide geographies are not in fact precise replications but filled with as much variance as there are individual imaginations. People claim they see all kinds of things all over the world that include dinosaurs, vampires, gnomes, floating eyeballs, enormous flying hotel UFO's and mermaids. What does this mean - that they all exist? Or does it mean, as the abduction phenomenon suggests, that people believe they are having very unusual experiences. The distinct lack of physical evidence for many of these sightings claimed by lone individuals do not add up to much, but does suggest that there are in fact issues of hoaxing, misperception, and, for reasons tied to our cultural history, outright delusion. But that's just my opinion.
