Physiological responses indicate that hypnotized subjects are not lying. It is dangerous. Standard hypnotic procedures are no more distressing than lectures. It has something to do with a sleeplike state. It does not.
Hypnotized subjects are fully awake.
Responding to hypnosis is like responding to a placebo. Placebo responsiveness and hypnotizability are not correlated. People with certain types of personalities are likely to be hypnotizable. There are no substantial correlates with personality measures. People who are hypnotized lose control of themselves.
