Hypnosis is very individual. Some describe a feeling of deep relaxation and rest. Others have the feeling they’re floating, or on the contrary, their body may feel heavier. Most of them have neither a sense for space nor for time.
I have never met anyone who claims that hypnosis was unpleasant. Some people just find it easier to go into hypnosis than others.
More on the question: Can everybody be put into hypnosis?
From my own experience I know that hypnosis is pleasant and beautiful.
