Creating a room

Rating: 10/10 (5 September 2013)

First I intend to post several thoughts about the tricky points in the movie.
Whether on earth can we use totem to distinguish reality and dreams?
Totum works because only the owners know its weight and way of balance so that they could tell the difference in dreams created by others. Joseph also explained in the movie: "in that way you will know if your are in someone else's dreams." But there are no single evidence showing totem functions in people's own dreams, which means even if Cobb's top stops spinning, he is not indubitably in reality.
Is the ring a sign of dreaming?
In dreams, people wear whatever they want: in hotel they are all suited up; in the third level they wear weight camouflages. Some argues that the ring only appears in Cobb's dreams but what is that to do with whether his "reality" is a dream or not? If Cobb himself believes that the world where his wife dies is reality certainly he would not wear the ring-no matter he is right or wrong about that point.
Why does Mal not wake Cobb up if she does go back to the real world?
Cobb once says he and Mal lose in limbo because they try to study the nature of dreams and thus build lots of them; sedation, in this case, certainly is demanded. Now we all know that when it comes to sedation hardly can one be waked up and the kind Cobb use could likely impair the ears.
Moreover, in a scene, Mal tells Cobb that the children are not real and Cobb is dreaming. He asks back:"if this is my dream why can't I control it?" "Because you don't know you are dreaming!" so she says.
Does this notable detail suggest that Cobb may live in a dream which he calls reality?
Well, all I said above is meaningless, isn't it?
Just like many other movies, TVseries, animations, to attract audience Inception offers a world of void. No one, however, could mix stories with reality, neither can he or she perfect the logic behind the stage. The screenwriter arranged a house where all the sets seem reasonable. But in the end, when the audience query what's behind the door, usually no answer is served, for even the screenwriter has not been there.
