Hypnosis and mind cintrol are very real. Hypnosis is easy to learn. There are plenty of good free courses on it out there. None are better than the Foundations course from HMI. Now, getting someone to do what you want without trance is much more difficult and requires lots of training. Some people teach courses on how to do it, but what they usually teach is rapport building, embedded commands and anchoring. There is a lot more to it than that.
Now, nothing will allow you to override someone's core values. The government dtd experiments with this starting in the '50s. Messed with a lot of peoples heads. They were trying to develop the "hypnotic assassian". Didn't work. Some test subjects wound up with severe psychological problems. The mind is a delicate thing. These are skills that you have to use properly. Careless use can be dangerous.
These are all skills that can be learned and developed. They are not magic. Just proper conversarion and language. Nothing will give you magic mind control Jedi skills. Vampire hypnosis is a thing of fiction, just like vampires are.
As always, just my humble opinion,
