My favourite story about Jung is this -
A prominent banker came, in great secrecy, to see the disgraced (at the time) CG Jung about a recurring nightmare, in which the banker was being chased by an enormous snake. Jung offered to go, with many psychological safeguards, back into the nightmare with the banker, who would speak to the snake. They did so, I think, under hypnosis.
Today, it's a common thing to go back into your own dream and find out what's going on.
The banker stood with Jung inside the dream, at a great distance from the snake.
"What do you want?" the banker called.
The snake answered, "Don't you know me? I was your pet when you were seven years old. We played wonderful games and had adventures. Why won't you play with me?"
There it was. The successful workaholic banker thought that play would ruin him. When he saw a form of play (his former pet snake, which had also grown large), the banker saw a menace to his successful life, i.e. a form of death. He was running for his life, only he had got life and death confused in his deep mind.
