Yea there is some speculation whether or not this started as a viral campaign much like district 9 etc, who knows, we wont know until we see a movie trailer or someone blows this whistle, to be honest id be kinda pissed if thats the case. If this is real im sure there is a real legit explanation for it, with all the things thats happend recentely with how the planet has been acting if you will i wouldent be suprised if its some sort of thing to do with the earth
just seems to creepy to be real when you think about it :lol I saw one video that was using the sound from another one, and in the fog you see what looks to be the tripod from war of the worlds show up, i thought it was hysterical :rofl
