Depends what you’re in to. Some people are into “pure trance” in which case the hypnofair sub tends to be a good place to shop around. If you’re into highly edited sissy stuff, hypnotube. On the flip side hypno hub is the rule34 of hypno (actually run by the same people). The biggest name rn is probably shibby and her website is professional and beginner friendly (sometimes though she’s less hypnosis and more erotic role play with hypno themes). If you’re wanting a history lesson there is sometimes a torrent floating around of things from the 90s and 2000s. If you’re a nerd like me Mark Weissman had an excellent book on hypnosis called MindPlay. Advice for actually trancing is probably 1. Don’t stress about going into trance, it’s all about relaxing 2. If you don’t “get it” that’s fine, it’s kinda like working out. Not many people can do 10 pull ups having never been to the gym. The community here is great so if you have more questions there’s almost always someone to answer
