No, hypnosis is a natural state that we spontaneously go into many times a day, a state somewhere between wide awake and fast asleep so it is impossible to get stuck in hypnosis, you will either wake up or fall asleep. Listening to your self hypnosis audios you will be guided into hypnosis and guided to wake back up again into a fully awake state. Do allow yourself some time after listening to your audio to return to a fully wide awake state if you are going to be engaged in something that requires a fully wide awake state, such as driving.
