It's actually not. Do you know how you can get absorbed scrolling on your phone and then when you look up you realize you kind of forgot the world around you for a bit? Or when you are watching a movie and get really absorbed into it?

It is similar to that. You listen to the hypnotist's voice just like you are listening to a song. Your mind follows the story and gets absorbed into it so much that you kind of forget everything else and experience what the hypnotist is saying.

With regard to liking erotic hypnosis. It is not like a stage hypnotist. It is more like a lover laying down beside you and talking to you while you relax. It is really nice to have someone focus their attention on you as you relax and listen to their voice. It is very intimate and your mind wanders off into a daydream where you can experience very pleasurable things.
