In hypnosis awareness is increased. The senses are generally enhanced (hyper-acuity) when a person is in the hypnotic state.
You hear any sounds in the general area and you are quite aware of what is going on.
When in hypnosis, you are fully aware of what is being said to you and you can reject any suggestion that is given to you at any time.
If you fall asleep you are not in hypnosis. Hypnosis might resemble sleep, yet it is not sleep, and it is in fact a state of expanded awareness.
