ILLUSIONS AND HALLUCINATIONS
Returning home from a scientific meeting one night, a college professor, who was noted for his concentration of thought, was still pondering deeply on the subject that had been under discussion. Upon entering his room he heard a noise that appeared to come from under the bed.
"Is there any one there?" he asked, absently.
"No, professor," answered the intruder, knowing his peculiarities.
"That's strange," murmured the professor. "I was almost sure I heard some one under the bed."
