How does this make you feel?

I will talk about the video "How Does It Make You Feel" from Air: http://www.azvideos.com/videos/air/howdoesitmakeyoufeel.html

There are some tubes filling up with red and white liquid, some switches changed of position, some things getting fired, explosions.

The images of people I can see, is a woman that their parts of her body are going back to their place.  At the end the head of the girl disappear and is replaced by a head of fish.

The letter of the song is very romantic; I think it is dedicated for the girl that is forming. I think that the explosions, the things getting fired can be the feelings of the author or maybe they can be like a factory creating the girl.

Initially, I think that the song is dedicated to the girl that if forming. But at the end I get surprised when I see that the girls head disappear ant it is replaced by a head of a fish, but I think that the reason why it is replaced is what the fish said at the end “Well I really feel you should quit smoking” something unexpected, so that’s why it changes to a head of fish, something unexpected.
