Leonard Shelby: I have to believe in a world outside my own mind.
I have to believe that my actions still have meaning, even if I can't remember them.
I have to believe that when my eyes are closed, the world's still there.
Leonard Shelby: Memory can change the shape of a room;
it can change the color of a car. And memories can be distorted.
They're just an interpretation, they're not a record,
and they're irrelevant if you have the facts.
Natalie: What's the last thing that you do remember? Leonard Shelby: My wife...Natalie: That's sweet. Leonard Shelby: ...dying. I can't remember to forget you.
Do I believe the world's still there? Is it still out there?...
Yeah. We all need mirrors to remind ourselves who we are. I'm no different.
