I always wonder when I see one of those hypnosis shows, where someone from the audience makes themselves a docile fool in front of a large crowd, whether they are stooges or it is the real deal. But I wouldn't volunteer to get hypnotised to figure that out, in fear of being the next person who stands imitating a dog in heat on such a stage.
The few people I’ve asked who’ve been hypnotized said it was true and had no reason to lie or trick me, and it seems true. But if the lens is “we already figured out all biology and physics so we can ignore the possibility of actual hypnosis (putting someone in a trance stage) being possible” then it’s hard to see things that there’s actually immense evidence for (eg the telepathy tapes).
There’s a good book about this called Reality is Plastic. It may give you a new perspective.
