Quote context

[...]

- When I was freed from Dachau, sick, delirious, I raved about a wonderful kind nurse named Anna who took care of me.

- Well, there you are, it's logical she's coming to see you tomorrow.

- But there was no Anna, I'd been nursed by a man.

- Anna was only a dream. And there was only one way they could have learned about her. By reading my subconscious mind.

- That's impossible.

- Why? A whole crew was thinking of home.

- Suppose the Martians read our minds.

- Yes, but if there are Martians...?

- If there are, they have us separated, each man in a different house. Sleeping, trusting, no one at the guns.
