Reread “surely you must be joking Mr Feynman”, considering the American thought control program was well underway, and messing with people’s minds, particularly prominent peoples.

- discussion of his adventures in the sensory deprivation tank, where he “crashed into” someone else’s experiences

- when going to sleep one night, a mob of others in his head were interacting with him. They offered to let him experience fully aware sleep, which he “tried” then refused as it didn’t seem natural to him (waking dreams is a skill the mind may master).

- talking to a recruiter, it is subtle, yet the recruiter asks the question about voices not because it means your crazy, rather the voices make people paranoid and unstable, and only a crazy fool would reveal this. Feynman mentions hypnagogia. The government did now want the great scientific mind of Feynman enlisting, no matter how enthusiasm for the noble intention.

Mr Feynman was obviously crazy. All of his opinions should be disregarded as nonsense.

But wait, he's a famous smart guy. so we have to take him seriously.

Oh it's tearing my science-loving brain right in half I tell you.
