some other people might say that if he was in dream his wife would be there. what I think is that he finally back with his children making his mind at peace with her death.
Actually, this is shown when he kills her in Limbo. He has finally come to an acceptance of her death and his own part in it, and she would not return in his dreams again like she had done at any other time (unless, presumably, if he was revisiting memories).
She would be - dead, and would not haunt his dreams any more.
Big problem I have with this movie...since its release people have been calling things that are within themselves "Inception"
I do agree with this, it's kinda stupid. People keep considering the "dream within a dream" the inception, when it in fact is what they are set out to do, that is the inception. Inserting the idea of Fischer's father wanting him to make his own firm and live his own life is what the movie is about, not going deeper or being within something. That is simply the method they have to use, the same way they also used several dreamscapes in their extraction of Saito's information.
They even describe it in the movie...
