The "And we can take this huge universe and put it inside a very tiny head: you fold it" part actually is a quote from the neuroscientist Rodolfo Llinas. It's part of his theory of visual perception.
Full quote: "The outside world is a projection, you put it there. It is not happening out there, it is happening inside your head. It is, in fact, a dream, exactly like when you fall asleep. We need to see, we need to perceive, we need to dream actively, because this is the only way we can take this huge universe and put it inside a very tiny head. We fold it, make an image, and then project it out"
