Hypnosis encourages an altered state of consciousness , by definition.
Consider carefully what the words altered state actually mean. A person is in a very different state of consciousness while working a crossword puzzle than when engaged in lovemaking. Going from any activity to any other will naturally result in an altered state of consciousness. Hypnosis is merely a tool to encourage altered states of consciousness. What is done with these altered states of consciousness says no more about hypnosis than what is done with a computer says about that computer.
