It would make more sense if the mirage showed people heading to the mountains. I certainly wouldn't have gotten the message to flee a coastal from seeing a mirage of a city. Ah, one could say, you weren't one of the chosen who received the telepathic message which provided more information.
In the example of the movie, Close Encounters, ZT offered it cited that certain people got zapped with a telepathic message. Does that mean that not all of the tens of thousands of people in town for the holiday weekend who saw the image that was visible for four hours didn't get the subconscious message, thus, weren't included in the full explanation of the message?
An argument could be, Ah, we said it was similar to but not exactly like Close Encounters. (underlined phrase is an example of leaving oneself some wriggle room, which means to leave oneself some room to maneuvre by clever or devious means: wriggle out of an embarrassing situation, esp. when the truth comes out. Lots of those kinds of words in ZT.)
Just for the sake of argument, let's assume they all received the telepathic message. Then why is the image inconsistent with the advice? Where are the mountains? And, going further, what kind of advice is it to seek a city in the mountains? Cities might be a temporary refuge now but why not lead them away from coastlines and into something more sustainable through the passage so they don't have to leave again, especially when the message appeared to be time critical? Hasn't it been a basic premise that cities, in their own way, are just as dangerous as coastlines during the coming upheaval?
Read the actual article. It says that mirages have been recorded in that location throughout history. Uh oh. A fly in the ointment. Why was this day any different?
Mist is involved in these events. See the link above for the May 2011 event and comments. Did you know Disneyland, back in the 80's, projected mist into the air which turned the air into a canvas to show their movies in the sky over the tall ship area. It was great fun, but even back then the technology existed.
There are way too many details for these to just be mirages. Hologram tech, or earlier Disneyland tech are the best possibilities. But, perhaps, it is a reflection, though not likely since an original would have to exist to be reflected. (Later, after one of msred's comments I could see that perhaps a sunken city could exist that sometimes reflects into the air under certain conditions like clear water and sunlight at a precise angle. But even as I type this I realize that mist is present and while the mist could act as a canvas to project onto, the presence of mist would mean sunlight could be blocked, but because of land configurations there could be exceptions. Anyway, an underwater city is the least likely.
But no matter the origin of the misty city, the ZT explanation doesn't make sense if one is trying to get people to do something. Just the telepathy would have been plenty enough, and much less confusing.
BTW, this earlier China mirage was in 2006. And five years later, what has happened? Tens of thousands of people witnessed the image and at least some, but logically more, received a telepathic message interpreting the mirage. Has there been a mass exodus? Has anything at all happened based on this grand warning? Nope. Nada. Negativo. Zip. Zilch. Zero.
My bet is enterprising business developers are playing on a natural phenomenon and now have the power to make it more realistic, so as to increase tourist trade in their area. What do you think?
