“Fools!" said the man, stamping his foot with rage. "That is the sort of talk that brought me here, and I'd better have been drowned or never born. Do you hear what I say? This is where dreams — dreams, do you understand — come to life, come real. Not daydreams: dreams.”
“I'd dressed up and hoped and I was so tired of doing that, so tired of dreaming and being unable to stop it despite the fact that I'd seen, maybe better than anyone here, what dreams could do to you.”
“Dreaming isn't wasted time. The waste comes when you have these wonderful dreams, but you don't do anything to make them real.”
“Coming true is not the only purpose of a dream. Its most important purpose is to get us in touch with where dreams come from, where passion comes from, where happiness comes from. Even a shattered dream can do that for you.”
“I dreamed a dream when I was sixteen and here I am, standing with my dream, feeling it come real.”
“Is there any way to be sure that your whole life has not been a dream? I don't think that there is. Typically we call some experiences "dreams" and others "reality" by contrasting them. Experiences that we call "real" are consistent and predictable. For example, people don't just get up and fly away in "real life" while they sometimes do in dreams. And it is not unusual for the experiences we have in dreams to jump around from one time and place to another, while those events we call "real" do not. But if your whole life has been a dream, then there is nothing to contrast these experiences with. In this case, the "dreams" that you recall each night are just dreams within the dream. And that contrast still holds. Even if your whole life has been a dream you could distinguish your nightly dreams from your "waking experiences" much of the time. But how do you know that you are not in Neo's predicament- that even your waking experiences are simply more dreams- just more predictable ones? Morpheus's suggestion seems correct. If you have never awakened from the dream to see what "real life" is actually like, you would have absolutely no way to discern that you are dreaming.”
