No, hypnosis is simply a state of extreme relaxation where a person is more open to suggestion. When a person is under hypnosis they will not do anything they would find morally objectionable under normal circumstances.
The person will remain under hypnosis until the hypnotist returns and reverses it.
that's pretty messed up. Go to the bathroom
No, the person still has will power, but they would do anything they would normally do or do with lowered inhibitions, such as they would do under the influence of alcohol.
No, nobody would do anything under hypnosis that he or she would otherwise be unwilling to do.
In theory, possibly. Everybody reacts differently under hypnosis. The password is stored deep in your memory somewhere, even though you have forgotten it. Hypnosis is a method of digging into the back of your memory. A quicker, and free, way to retrieve a password is to click the 'forgot password' button on the website. Hypnosis for a password is a bit extreme.
Yes. Despite legends to the contrary AND a LOT of bad movies.
no
Somnambulist is a person who engages in somnambulism. Somnambulism is the technical term for sleepwalking, which can occur under either hypnosis or normal sleep.
Hypnotic trances are not permanent; the person will come out of it naturally. Perhaps the person will fall asleep and then awaken, no longer in the trance. If you have concern that a person is in danger of harm to self or someone else, then do what you can to prevent the person from leaving or call the authorities if the person does leave. The prevailing wisdom (not a fixed law) is that a person will not do under a trance anything that the person would not normally do.
Is very open to suggestions.
Hypnosis really only works for people who are very imaginative and have a rich fantasy life, so hypnosis can't affect people who are completely against that sort of thing. Many people believe that hypnosis is good for recalling forgotten events but the truth is that usually it doesn't work for that purpose and responses to memory recall are only due to leading questions the hypnotist asks. For example: If a hypnotist asks if a person was beaten as a child, the person under hypnosis may believe that they were because it was asked of them like as if it had happened. They tell themselves that that was what they wanted to remember and they alter their actual memories to support the claim. This is why hypnosis is no longer really trusted for criminal cases and important memory recall.
