"Absolutely. All of us. We can go just so far. Where the mind is
strong and very sound we can go further than when it is not. Some
men, for instance, lead lives that would break you or me. Was there

"Yes." Doctor David's voice was reluctant.

"The mind is a strange thing," went on the little man, musingly.
"It has its censors, that go off duty during sleep. Our sternest
and often unconscious repressions pass them then, and emerge in the

Does the person in this case dream? That would be interesting,
perhaps important."

"I don't know," David said unhappily.

"The walling off, you say, followed a shock?"

"Shock and serious illness."

"Was there fear with the shock?"

David hesitated. "Yes," he said finally. "Very great fear, I
believe."

"I see," he nodded. "Of course the walling off of a part of the
past--you said a part--?"
