Unless you give these or similar pre-hypnotic suggestions, the subject might develop uneasiness and manifest unpleasant sensations from which the practician ought to protect him. There is no reason why the hypnotic state should not be effective as well as pleasant. I remember my first attempt at hypnotizing, when I knew very little of what to expect. The subject, a young man of twenty, entered the state surprisingly easily but immediately afterward began to groan and to move about. Naturally, I became somewhat frightened and decided immediately to awake-him. But for a minute or so, neither could he get out of the trance nor could I arouse him. Nothing more serious happened, of course; nevertheless, I promised myself to take, henceforth, every precaution against similar accidents.
