Hello Jai, yes an intriguing video ... i think people do this kind of thing because, well it's intriguing ... i suppose it all depends whether we believe, perhaps we should suggest it to James Randi, you never know if it works we may win the one million dollars !

There is obviously some kind of energy involved, either a known energy operated consciously or a natural energy, operated consciously or unconsciously, that has not yet been explained by scientific means.

have fun :)

p.s come to think of it this video reminds me of the Uri Geller levitation demonstration, this time the energies are directed towards the source of light, that is, the candles ... i do believe there is a phenomenon of subtle energy entering into resonance ... a mirror is a sheet of glass backed with a shiny metal backing and this set up is well known to create a subtle energy flow (similar to how a battery works), here's a simple model;

and mirrors reflect not only light but also sound ... light travels a whole lot faster than sound creating a tension (void) between the two energies ... and subtle energy (dark energy) rushes in to fill the gap.

Roberto Zamperini describes how to create a subtle energy flow using a pile of alternating small round sheets of paper and aluminium, a similar phenomenon is created with a mirror ... there is also a virtual inverted triangle effect, the triangle formed by energy travelling between the girl, her image and the light forces ... notice that this creates a downward gradient, that is, towards the hot center, and the hot air rising increases the void effect ... sound and light are always accompanied by large quantities of subtle energies ... voilà, i hope all this makes some kind of sense to you ... in any case that is how i feel it works.

If we can get James Randi to participate so that his energy actually accentuates the phenomenon then we come home with a million dollars ... pure folly :)

From a scientific point of view it would be interesting to have kirlian style photos of the circulation of energy whilst doing this experiment ... here is an example of a kirlian photo of the energy of a pyramid;

I think that some of this stuff, as this scene from this movie, are intended to convince those who have induced split personalities to take the memories of what has, and is, being done to them and blame them away on the paranormal, allowing the actual guilty party to stay hidden in plain sight.
