Inception Ending or Beginning

Inception is one of my favorite movies.

It is beautiful.

Features great stars.

And it makes You think.

Everyone has their dreams. Even if they do not remember.

The ending of the movie with that whipping top...

But I can see alternative ending or beginning of Inception 2 if that is coming.

If You are careful, than You notice that after Di Caprio wakes up in the plane, he is silent.

The craziest moment would be if he came back home, saw his kids and then... there was also his wife.

Than everything would be his dream on international flight.
Those people were strangers to him and so on.
And his wife did not jump...

Or it can be used as beginning of Inception 2.

And the main idea is to find out if Leo was sleeping all the time, or it is still a dream.
