Batman: The Animated Series1992

[after the Batman impostor is revealed]

Bruce Wayne:
The Mad Hatter?

The Mad Hatter:
Congratulations are in order, I suppose. And you're right! This is a dream, a very special dream.

Bruce Wayne:
Then you know everything about me?

The Mad Hatter:
I do! But I'm only a part of your dream. The mind control apparatus I've hooked you to reveals nothing to the outside world - it's purpose is to create an ideal fantasy world for you!

Bruce Wayne:
Then you're not the real Mad Hatter.

The Mad Hatter:
No. Just a figment of your imagination. But that doesn't mean I'm not real - in this dream world!

Bruce Wayne:
Make it stop!

The Mad Hatter:
I'm crushed! You don't like the fantasy world I've created for you?

Bruce Wayne:
It's not real!

The Mad Hatter:
Ah! Are you the dreamer or are you part of someone else's dream? That's exactly the question Tweedledee put to Alice in 'Through the Looking... '

Bruce Wayne:
This isn't some silly storybook!

The Mad Hatter:
Oh, but it is! It's a beautiful story! You have love, wealth, a family, all you ever wanted! Your own private Wonderland!

Bruce Wayne:
NO! I won't live a lie! No matter how attractive you make it!
