How does it makes you feel?

i have seen the video called "how does it makes you feel?" by AIR.
It is difficult to understand, the lyrics is an useful tool, it helps you to understand a little of the video.
It makes me feel like rare.Like if i need something that is missing to complete. I think that the images had different meanings, metaphorical i mean. I think that all that cables and lights are representing the girl and the smoke is passing through her and separated her.
when the fish appeared it confuse me. I think that it is a metaphor of she becoming a fish.
In conclusion i think that all is because of smoking. so the mayority of people when you ask how does it makes you feel? they will answer  that they wont smoke.
