Some people say that Inception's ending is incredible, because the gyro didn't stop shooting at the end of the film. Because if the gyro doesn't stop, it means it's still in a dream; If top can stop, it means that the protagonist is back to reality. However, the whole movie didn't say Cobb's totem was the top! And whose totem is this gyro? Cobb's wife Moore. It was precisely because Cobb moved his wife's totem that she could not distinguish between reality and dreams, which indirectly led to Moore's suicide ... But although the gyro in the film was teetering, there was no scene to stop it.
Since the gyro is not Cobb's totem, why does Cobb take it with him every time he performs a task? That's because Cobb, as an excellent dreamer, let everyone think that his totem is a gyro for safety reasons, but in fact he is hiding his real totem.
How to prove that it was Cobb's dream in the end? The film gives two hints.
The child's face
From the beginning of the movie, when Cobb went to find Saito trapped in the abyss, Cobb's two children were always behind. No matter in Cobb's own dreams or in other people's dreams, the children Cobb saw just passed by in the back.
But after Cobb returned to his home in America, he finally saw the faces of the children he dreamed of. This can prove that the ending is in reality rather than in a dream.
Cobb's totem
Since gyro is not Cobb's totem, what is his totem? Although the film didn't say it, it can be seen that his totem is a ring-a ring that exists in dreams but doesn't exist in reality.
In Saito's dream at the beginning of the film, Cobb obviously wears a ring. At the end of the movie, Cobb didn't wear a ring when he passed the security check.
So director Christopher Nolan didn't fool us. Cobb finally returned to his home and hugged the children who had not hugged for a long time.
