Power of suggestion someone?
All I can think of when seeing that movie (and the extremely poor quality, so poor you can hardly see anything at all), is that it is the same as all those so called proof of ghosts photographs and so called subliminal messages in backwards music and what not.
When someone says you'll see this and that (or you hear this and that) and you show them a blurry photo 75% of people will actually see the thing which is said to be there, eventhough it isn't there at all....
Conspiracy theorists will have a field day with this one though... I rather wait for the "Seconds from disaster" docu on NGC...lol.
PS: I even hear a horse (police horse?) at some point (1:37).... Then again, to keep in the same conspiracy trend: it can be the dead scream from a little girl who is stabbed with a knife too.
PSS:

those comments from ModderZ7 paint a very different (far more believable) picture
