How can I understand Inception?

Need to know the "rules of the game" of this movie.

Inception opens for 2 minutes: Cobb wakes up at the seaside and there are two children playing in the distance. A soldier came and took him into the hall of a wrinkled old man, and there were a series of dialogues-in fact, this part only reversed the montage to attract the attention of the audience, with wonderful pictures and shocking plots at the beginning and foil plots at the end.

Directly from the second short story, we can understand the game rules of this movie-Inception. Cobb and Saito are on a big ship. Cobb tried to steal the secret documents in Saito's thoughts, but was betrayed by Cobb's subconscious mind, his dead wife Mal, and the action failed. Saito woke up and found that the carpet was made of different materials, so he found that it was love, love and love, and Cobb failed.

These dreamers can enter other people's dreams, steal some business secrets, or implant some kind of thinking. Qi Teng's energy company is about to be overwhelmed by Fisher's father's company, so Qi Teng wants to hire Cobb to help him.

The filming plan of this film was born during the filming of Batman Prequel 2: The Dark Knight. Christopher Nolan once considered working with his close partner Christian Bale again, but Christian Bale has other shooting plans, because he wants to shoot Terminator 20 18, and Christian Bale has other shooting plans after that.

So he suggested that Christopher Nolan find other actors he likes to play the leading role. At this time, Christopher Nolan thought of another actor, Leonardo DiCaprio, who he liked very much but had never formally cooperated with.

When Leonardo DiCaprio only knew that the film was written and directed by Christopher Nolan, he decided to star in it. Even then, he didn't know what the theme of the film was.
