Question:

“Under hypnosis can one loose their own identity and become like a mindless zombie, reacting only to the commands of her Master?”

Answer:

This question is rather involved.  The answer is possibly.  Some subs love this feeling of total submission and trust.  For a short time, during a session, it is possible.  However, once the trance is over, the "zombification" will also end. 

If you are worried about losing you identity completely, that really can’t happen without a lot of reinforcement.  I'm talking about having you spend time 24/7 with the Hypnotist, and he is constantly putting you under and providing reinforcement.  It can not happen casually.

Question:

"Are there specific questions a slave should ask a potential Master to know if he is truly a hypno Master?"

Answer:

The questions you should ask would be similar to the questions you'd ask a hypno-therapist and a Master:  Where did you get your training?  How long have you done hypnosis?  How long have you done D/s?  Are you a certified hypnotist?  How many subs do you have or have had?  How many of them were hypno-subs?  What kind of punishments do you usually give out?  These are basic questions but of course, you can add more.  Remember, it's your safety, privacy and pleasure that is important.

Question:

"Are there any negative signals a sub should look for?"

Answer:

There are several:

Like with any Dom, if s/he starts off with the "On your knees, bitch" type of attitude, don't go any further.  If they are not a good Dom without hypnosis, they will be a worse one with it. 

Also, like any non-hypnosis Dom, if s/he does not offer a safe word, that is a warning.

If the Dom wants to put you under immediately without any kind of discussion of your limits.  For instance, when I put someone under the first time, it is usually just three tests, and I discuss each one with the subject before I even start the induction.  A good Dom should start this way as well.  If the Hypno-Dom does not talk to you about your desires, your limits, or your fears at all, that is a big tip off to stay away.

When you get hypnotized for the first time and you do not remember going under, or you do not remember what happened, or you lost time or a combination of any of those, (unless you specifically asked for that effect), steer clear.  For the first and even several sessions after that, you should remember everything.  Much later in the relationship you can forget things and lose time.  But again, that is much, much later when trust and communication has been established.  And even that far into the relationship, there should be a trigger word that removes the memory loss.

Finally, the first few post hypnotic commands should be harmless and limited.  Again, once trust and communication has been built, then more daring post hypnotics can come into play
