Note: I've been informed that Kwan Yin passed away in 2008. Her web site has since been taken down, but this article contains some good advice.
Talking to subs, I have heard a lot of limits. One of funniest limits was my first slave's limit "relatives" he said he wouldn't do anything D/s or sexual with relatives. lol Some D/s limits are no blood, no scat (excrement), no pain, no humiliation etc. In D/s we know our limits and discuss them freely before anything takes place. But what about we the hypnofetish community?
We need a way to discuss in advance of hypnosis, what we would and wouldn't like to have happen, as well. Although anything done with hypnosis can be undone, it's usually not pretty when it has to be undone, and that's best to be avoided. Many subjects forget little parts of trances or whole trances. You have to be able to trust your hypnotist not to take advantage of the situation and slip in a little unconsensual suggestion. That means the hypnotist must be trustworthy in the first place.
The whole point of discussing limits in advance is to establish what is being consented to by both parties. That is what is meant by consensuality. If you don't know our guidelines are SSC, they stand for Safe, Sane and Consensual. By consensual we mean informed consent without coercion or influence. That means consent while you are out of hypnosis too, and haven't been in hypnosis for at least 20 minutes. It takes a while to come out of hypnosis. It's OK to change your limits in time, but think about long and hard, when you're alone and be sure it's what you really want.
The wikipedia says "Informed consent is a legal condition whereby a person can be said to have given consent based upon an appreciation and understanding of the facts, implications and future consequences of an action. In order to give informed consent, the individual concerned must have adequate reasoning faculties and be in possession of all relevant facts at the time consent is given. Impairments to reasoning and judgement which would make it impossible for someone to give informed consent include such factors as severe mental retardation, severe mental illness, intoxication, severe sleep deprivation, Alzheimer's disease, or being in a coma." (or being in a state of extreme suggestibility like hypnosis where the hypnotist has increased influence)
What are some things you should watch our for? Unless you specifically CONSENT IN ADVANCE they should NOT give:
