Your friend tells you she is seeing a therapist who wishes to use hypnosis as part of her therapy. However, your friend is concerned that she might be hypnotized without knowing it. What might you tell her?

a. Don’t worry. Hypnotists can only control their patient’s behavior about 40 percent of the time.

b. Be careful. Hypnotists are in control of you while hypnotized.

c. I actually hypnotize myself, and I cannot be hypnotized against my will.

d. Don’t worry. Hypnosis is just an illusion and doesn’t really work.
