Answer:
Some things that hypnosis can do are, well basically anything. But one thing that it can not do is make the person who is hypnotized do anything against their will. Meaning that if you want them to be a slave forever, they will not do it, unless they want to. Also, you must note that when you hypnotize someone, they will not have super human abilities. For example, the hypnotized victim can not lift a bed with one finger. So a hypnotized person can put away your clothes, or you can make them think they are a cat, but you can't make them be a slave and make them do something against their will.
