Covert Hypnosis is the ability to hypnotize people without them ever knowing it. With hypnosis you can manipulate another person's psyche and influence his or her decision making process, desires, wishes, and perception. So I think you might already know some about what caovert hypnosis is capable of, but here I need to address some of the limitations built into covert hypnosis, some of the myths that people have around hypnosis. People do think that covert hypnosis is an all-powerful force that controls people's minds, is capable of leaping tall buildings, and doing all kinds of crazy things. As a hypnotist you really need to understand what you can achieve, and what the limits are to what is possible with hypnosis.
One of the first limits is this idea of mind control. Mind control hypnosis does not exist. When someone is hypnotized, they are not your slave. They are not someone who has to do everything you tell them to. In hypnosis they merely want to do more of the things you suggest to them.
However, there are limits. For example, you cannot get someone to break their moral code under covert hypnosis. You can't force someone to commit a crime like murder or theft if they wouldn't be willing to do that crime under normal circumstances anyway.
The reverse is also true. You can't treat criminal behavior with just covert hypnosis. You need to have the person's will included in the process. If someone is, for example, a kleptomaniac - that is to say, someone who has to keep stealing things, but they want to stop stealing - then hypnosis can be used tremendously well.
If someone is a thief and doesn't care about being a thief, then hypnosis will do nothing to change that person. If it worked differently then we wouldn't need prisons. We would just send hypnotists in and we'd solve all those problems that are currently faced by the prison population.
In covert hypnosis, your mind is still under your control. The difference is that in covert hypnosis you get to experience things that you otherwise would not allow yourself to experience. As a result, you get to enjoy a different kind of life. You get to test out what life would be like if the world was different. If you like it, you get to keep it.
