The only danger in hypnosis is likely to be found in hysterical persons. They will,if aroused, often fall off again into a helpless state, and continue to do so for some time to come. It is dangerous to hypnotize such subjects.
Care should be taken to awaken the subject from hypnosis very thoroughly before leaving him, else headache, nausea, or the like may follow, with other unpleasant effects. In all cases subjects should be treated gently and with the utmost consideration, as if the subject and operator were the most intimate friends.
