[Cobb, Eames, Saito, and Yusuf enter a room with a dozen dreaming people]

Eames:
Ten, twelve all connected by the machine.

Yusuf:
They come every day to share the dream. [An old man slaps one of the dreamers, who does not wake] You see? Very stable.

Cobb:
How long do they dream for?

Yusuf:
Three, four hours, each day.

Cobb:
Dream time?

Yusuf:
With this compound? About 30 or 40 hours, each and every day.

Saito:
Why do they do it?

Yusuf:
Tell him, Mr. Cobb.

Cobb:
After a while it becomes the only way you can dream.

Yusuf:
Do you still dream, Mr. Cobb?

Eames:
They come here every day to sleep?

Old Man:
No. They come to be woken up. The dream has become their reality. Who are you to say otherwise?

Cobb:
[to Yusuf] Let's see what you can do.
