Student v. Professor

From The Black Box Notes: On Dream Derive-ing.

The student (it could have been me) asked the professor once:

Why do we dream?

The professor, who was not only a learned man but also a fully qualified doctor, did not wish to bore everyone rigid.

We dream, he said, because the dream is more real.

The student, however, was not happy with this answer.

Professor, I asked the question, why do we dream?

The Professor, who was growing impatient, said:

Why do you ask me the same question?

Surely if the dream was more real, said the student, we would live it all the time.

Bravo! snapped the Professor. It is a question of survival!

Then we dream for our survival?

The Professor turned his back and did not answer.
