Christopher Jonathan James Nolan (born July 30, 1970) is an English film director, screenwriter and producer. He is known for writing and directing such critically acclaimed films as Memento (2000), The Prestige (2006), Inception (2010), and rebooting the Batman film franchise.

Director Christopher Nolan first developed Inception , based

on the notion of "exploring the idea of people sharing a dream space — entering a dream space and sharing a dream. That gives you the ability to access somebody's unconscious mind.”

Furthermore, "being able to extract information from somebody's brain would be the obvious use of that because obviously any other system where it's computers or physical media, whatever — things that exist outside the mind — they can all be stolen ... “

Dom Cobb, a professional thief who specializes in conning secrets from his victims by infiltrating their dreams. Cobb leads a team consisting of Arthur, Ariadne, Eames, Saito, and Yusuf, with the goal of influencing Robert Fischer's actions via his dreams.

Ariadne, a graduate student of architecture who is recruited to construct the various dreamscapes, which are described as mazes.

Mallorie "Mal" Cobb, Dom Cobb's projection of his deceased wife and a frequent, malevolent presence in his dreams. As the film's main antagonist, she is a manifestation of his guilt about the real Mal's suicide. Dom is unable to control these projections of her, challenging his abilities as an extractor.

Is it possible to directly access someone's dreaming mind?A device does already exist that can effectively read someone's mind. A functional MRI scanner takes snapshots of brain activity, and then the software recreates images of what the subject was looking at.

Hypnotism therapy is a process used to access someone’s subconscious mind and change the way he looks at the world. It is used to treat everything from chronic pain to depression, and sometimes it's even used to summon repressed memories from deep within a person's mind. The hypnotist will generally require a patient to focus on something and relax while speaking to him and guiding his thoughts to put him into a hypnotized state. Contrary to many popular beliefs, the hypnotized individual will generally remember the experience perfectly.
