I see this a lot, it is one of the most common questions in the Discord server, I get emails about it.
I'm not going to minimize your experience and say "yes you can", but "yes you can."
Now, unlike in media and fiction hypnosis is USUALLY not possible with no knowledge of it, with no cooperation toward it. You're going on a trip with me, you're letting me give you cues and scenery and all the trappings of a story, a conversation.
So, hypnosis "fails" from your perspective for all the same reasons a conversation might fail.
Lack of communicative skill on either of your parts, hypnotist or subject - nature of the speaker just not meshing with yours, anything that might get in the way.
Or you're distracted or hyper or moving around a lot.
Or you're "Seeking proof" and saying "Well how do I know we're REALLY having a conversation?" which will put a damper on any conversation.
Skill develops with time, but think of it as a conversation, act of storytelling, a movie played out for the mind, an experience where you let go of preconceived notions of what should be happening, and accept what does happen instead. Listen, listen as you would if someone were talking to you normally, and attempt to cooperate and create.
Even if you only ever "get relaxed" instead of getting more than that, relaxing is a difficult and wonderful thing.
When in doubt, start with the premise that you're already able to enter trance and you spend a lot of your time trying to avoid it. This one has the benefit of being true.
This is the only answer I'm capable of giving to this question: you can be hypnotized, if you don't move around and ditch things that would snap you out of trance and might draw attention away from the words, and treat it like a conversation where there might happen to be an aroused or relaxed tingle growing in your head. Normal as can be, until its not, and by then it is quite pleasantly too late to be bothered by your own mind when your body has achieved what you've been looking for.
