One of the best recent films to deal with unlocking brain potential is "Inception," the summer blockbuster director by Christopher Nolan. This film ultimately deals with the power of dreams, which demonstrate the near limitless power of the human mind.
The film follows Dom Cobb (Leonardo DiCaprio), who works as a kind of "dream thief" for major corporations. Together with his partner Arthur (Joseph Gordon-Levitt), Cobb can enter the minds of his targets and extract valuable information resting in their subconscious. The duo, along with other people who work in their top-secret field, use a chemical that allows multiple people to share dreams together.
Cobb and Arthur use their full brain potential to stay lucid in the brains of others and manipulate them into giving up sensitive information. However, they are caught in the beginning of the film by one of their targets, Mr. Saito (Ken Watanabe). Saito then hires the team to perform "inception," which is the actual planting of an idea in someone else's mind. In the world of the film, this is a much more difficult technique to pull off, leading to the main plot of the movie.
The epic scale of Inception coupled with the mind-bending dream worlds led to the movie being a blockbuster smash. Even more than a year later, the ambiguous ending has left people talking and craving a sequel.
Obviously, we can't enter a dream world with other people, like the characters in the film do. However, the overarching concept of dreams really does speak to the concept of human brain potential. While the worlds may not be as vivid and exciting as the ones shown in Inception, we do create dream worlds with our minds every single night we go to sleep, which give a hint of the unused brain potential that everyone has.
