I have studied hypnotism as hypnotherapy, not stage hypnotism, but it's in there. I'm not sure if previous posters were in disbelief about hypnotism working. Essentially, 50% of the population is relatively easy to hypnotize. The other half need to have it applied in a way that gets past their "critical mind". For the record, professional hypnotherapists don't claim validity to past life readings and things like that, they definitely have some forms about false memory syndrome, but there have been some ongoing and uncanny results in terms of people having skills they didn't have outside of hypnosis, and even speaking languages they've never heard before. Generally speaking, past life regression therapy is more about symbolism for the client to get past trauma.
That said, I am still skeptical that Mr. Brown was able to hypnotize a group of people to pull off a fake armored car heist. I do think that there could have been some additional things applied off camera in hypnotism that could cause people to do this. It's still a long-shot, from what I have learned.

I am more interested in the psychology behind these "mentalists". I just don't think all of these people could be actors, eventually, there would be too much of a backlash, one would think. In this video, Keith Barry seems to make people believe that they are being touched when it is really the person next to them that are being touched. There is another instance where a coke bottle seems to break with someone's mind. I don't know how to debunk it, but I've watched other things about Mr. Barry doing "dating game" tricks, making people more aware of subconscious cues that would cause one to know things or lead things in a conversation with a potential mate. This is a bit more interesting than magic tricks to me. Barry is definitely a stage magician, there is even a video of him failing to get out of being tied up and almost dying from asphyxiation, but the psychology part interests me the most.

As for ghosts, I spent the night in a haunted cemetery, reportedly one of the most haunted cemeteries in America, Bachelor's Grove. I went there as a skeptic. I thought "If there's anything out there, bring it on", and I saw almost everything I have ever read about; ongoing things, a bride and groom dancing around in circles for hours, hooded figures hovering around, orbs, a yellow man that kept exploding and reforming over and over, a disappearing house, all kinds of crazy stuff. I drew pictures of it in the moonlight, but like most stories like this, it is purely anecdotal, and any film I shot with a disposable camera, didn't show up. Even if it did, it wouldn't change anything. I would be curious if anyone has data on skeptics going ghost hunting at extremely haunted places and finding nothing. I don't see that happening, at least not in some places that I have been told are almost constant with phenomena at night, and even during the day.

The most conclusive material I have read suggests that Electromagnetic Frequencies or "ionization of the air" cause strange things to happen, perhaps from subsonic frequencies they project, which cause the retinas to slightly vibrate and possible trigger the brain in some way.

As for "psychic phenomena", I think there are some interesting developments with quantum physics as it relates to the concept of "collective unconscious", and if also the claims of "ancestral memory", that rats have been tested to seem to have memories of their parents, and so forth, it could give way to some new developments eventually, beyond the anecdotal.

I could keep going here, but I will leave it at that. Experience is quite convincing for me, but I don't necessarily intend to change anyone's mind. I'm more interested in staying on my toes.
