After doing a bit of reading on this fascinating subject, I've decided to post the more interesting things I found in my research in a nice thread. First, let's get some of the most popular myths about it out of the way.
1. When you're hypnotized, you still retain your morals and values, even considering that your suggestibility increases.
So, for example, if I hypnotized you, gave you a gun, and told you to shoot me in the head, unless you had no problem with killing when you were not hypnotized, you will still refuse to shoot me and may even very probably wake up out of hypnosis for me even giving you such a suggestion. Nevertheless, as said above, suggestibility DOES increase. So while you may not do anything morally wrong by your standards, you can still be suggested to do some crazy things like jump on a table or act like a chicken.
2. When you're hypnotized, you're actually much more conscious instead of less.
So no, you don't fall unconscious or into any sort of sleep state at all. However, all the hypnotized person's worries and doubts do vanish away completely as they focus on a subject completely in their relaxed state.
3. Hypnotherapy sessions needed range anywhere from 1 to 9 to 19
It really depends on the person, the problem, and how long the problem has existed, not including several external factors that may need to be worked through altogether such as a hard home life.
4. Self hypnotism is the same thing as meditation.
You see, hypnotism can be best described as coming into a very, very focused state that's also characterized by increased suggestibility. The difference between normal hypnosis and self hypnosis though is that the latter is guided by a third party while the former is guided simply by yourself.
5. When used properly, any hypnosis can be quite powerful.
People that are under feel incredibly relaxed, have their power over their imagination increased greatly, and can immerse themselves in and focus on certain subjects to the exclusion of most all else.
And that's about it. Let me know if you guys have any questions.
