No. People can't get stuck in a trance. Has anyone ever gotten stuck in a movie, story or a book? Has anyone ever gotten stuck in a dream?
Hypnosis is a natural and beneficial state much like meditation. No one has gotten stuck in meditation, however they could have had a guide take them deeper into that state and utilized it for subconscious conditioning.
If you would hypnotize someone and leave them in trance they would either fall asleep if greatly needed or would arouse soon depending on if anything called their immediate attention. People tend to report they love the feeling and could remain there for more time if they had the chance.
