“COBB: Our dreams feel real while we're in them. It's only when we wake we realize things were strange.Ariadne gestures around them-ARIADNE: But all the textures of real life-the stone, the fabric... cars... people... your mind can't create all this.COBB: It does. Every time you dream. Let me ask you a question: You never remember the beginning of your dreams, do you? You just turn up in the middle of what's going on.ARIADNE: I guess.COBB: So... how did we end up at this restaurant?”

“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.”

“I met you in dream." She says."You're right. But here we are, back to the real world.""I was so afraid you will never remember me in the real world. People usually forget about their dreams once they wake up.""Not me. Not you. Besides, maybe this none of us woke up. It doesn't mean we can't make it real.”

“Clare on Henry:Do you ever wonder if I'm real? Maybe I'm dreaming of you. Maybe you're dreaming of me; maybe we only exist in each other's dreams and every morning when we wake up we forget all about each other.”

“Dreams are only dreams until you wake up and make them real.”

“How do we know we're not people in a movie?' she asked.I looked at her not knowing how to reply.Mama, [...] how do we know that things are real?'Great. Now we have a junior existentialist in the house.Well, we don't know. We just have to hope that what we think is real is real.'But how do we know?' she asked, insistently.Ah, a scientist, who wants empirical evidence.We don't know. We just have to hope.'Mama, how do we know things aren't a dream? You know, how sometimes life feels like a dream? Do you ever feel that way?'Yes, sweetie, I feel that way all the time.”
