Director Christopher Nolan recently delivered a commencement speech to the graduating class at Princeton University, which prompted the recent graduates to chase reality and not dreams.

Nolan being notable for huge films such as 'Inception' and 'Dark Knight' came off almost uninspiring in his speech for what awaits the recent grads next.

"In the great tradition of these speeches, generally someone says something along the lines of 'Chase your dreams,' but I don't want to tell you that because I don't believe that," he states. "I want you to chase your reality."

He even drew references to his 'Inception' film during the speech, stating that dreams are "subsets of reality."

"I feel that over time, we started to view reality as the poor cousin to our dreams, in a sense. ... I want to make the case to you that our dreams, our virtual realities, these abstractions that we enjoy and surround ourselves with - they are subsets of reality," he explained. "The way the end of that film worked, Leonardo DiCaprio's character Cobb - he was off with his kids, he was in his own subjective reality. He didn't really care anymore, and that makes a statement: perhaps, all levels of reality are valid. The camera moves over the spinning top just before it appears to be wobbling, it was cut to black."

"The point is, objectively, it matters to the audience in absolute terms: even though when I'm watching, it's fiction, a sort of virtual reality. But the question of whether that's a dream or whether it's real is the question I've been asked most about any of the films I've made. It matters to people because that's the point about reality. Reality matters."

The director ends the long speech by closing on a Batman joke.

"The most important thing about Bruce Wayne - yes, he attended Princeton, but he didn't graduate," he said to roaring applause. "So as of tomorrow, you are all already better than Batman!"
