some interesting ideas from inception

Rating: 9/10 (25 October 2010)

Recently I saw the film and read some comments ,presenting some of new ideas,though all of these are not the key point of the film ,anyhow they are interesting viewpoints...
1. The inception must be operated in at least level 3 where there is less consciousness and more subconscious in order to avoid the consciousness during the inception .Conversely, since there is no consciousness ,how can the new idea be accepted by the consciousness? for example ,if the new idea is planted in level 3,then the new idea will be in the subconscious of level 3 forever ,and in the real world the new idea will not be realized by that man ,maybe there is only some vague fragments or unsure feeling.only when it comes to the level 3 can he realize the existence of the new idea .
2. we know that the mind would speed up as the dream goes deeper,it means we can do more things in a very short time in the dream world.so why don't we study in the dream? I think there must be some side effect as the mind speeds up,maybe it would shorten the lifespan of brain in the real world ,that is if the speed of mind is 10 times that of the previous one,then the speed of growing old of the brain would be 10 times that of the previous one,and also that would consume more energy than before ,therefore the dream can't go deeper unlimitedly with the limited energy .
3. The so-called inception in this film is laborious,it's not by changing the consciousness directly in the real world ,but by changing the subconscious in the deep level dream world.and all of these are supported by the dream machine .this kind of high technical device can automatically make people get into clear dream world, and it also can connect many people's dreams together to produce a so-called common dream ,and even can control the time of dreaming ... I think the most difficult part is common dream ,because it need to precisely find the millions of nerve cells which produce the dream, and to connect them between different people in an electrical and biological way.since the science and technology has developed to this level ,why don't just replace or change part of consciousness directly in the real world conveniently .maybe the science in the film is not good enough to decode all parts of consciousness and change them ,it can only connect and invade the certain part that produce dream...
4. in the film,the main reason why people can't tell the difference between dream and reality ,is that the dream is so clear and many people's dreams can be connected together via dream machine.but outside the film the dream is so vague.in the film, since we can get clear common dream and do anything we want,why don't we stay in dream forever,or just develop it as an interesting virtual game...
5. about the totem ,I think it's unreliable,it just can be used as a quick way to identify but not a stable way .because even in the reality the totem can also be modified by others.in fact ,no matter how real the dream is you still can recognize it as long as having enough time .maybe as the dream goes deeper the consciousness wound become vague which increase the difficult of identifying ...
