When a person hears about hypnosis they are always worried about it being something crazy or something that is similar to mind control. People always assume that hypnosis is the thing they watch on television that gets people to act like animals or the thing that makes people feel like they are trapped in their body without actually having any sort of control over themselves. Hypnosis is not actually like this and is a technique that a lot of counselors and therapists use to help other people.
The way stage performers use hypnosis is also legitimate but is extremely exaggerated, sometimes to nonsensical proportions. Basically what hypnosis will always let you do is that it can help you either get yourself or another person in to a mood where they are a lot more open to suggestions. When a person is more open to suggestions they are willing to do more and talk about more than they would if they were uncomfortable and tense.
Hypnosis can have a lot of uses for a person. It could help you make friends in a way as you will be able to help people feel comfortable around yourself and you will be able to do a lot more than you otherwise would do. Hypnosis can also be used on yourself so that you are able to put yourself in a state where you can truly look at who you are as a person and then work on yourself. Hypnosis can be done in a pretty easy manner as well. Most people would think that it is something otherworldly but it can be learnt. There is even a Buzzfeed article which features a number of different books that you can read on hypnosis. Just remember not to believe everything you read about hypnosis though.
