Hypnosis fetishism has a large overlap with mind control fetishism, which in addition to typically unrealistic, fantasy depictions of hypnotic control, may include magic (telepathy, vampires) or fictional technology (brainwashing machines, robotization) as plot devices. Hypnosis and mind control fetish content has been shared on the internet since its early years, as in a 1997 survey of stories from alt.sex.stories which found that "five percent of stories involved some kind of mind control (such as hypnosis, the use of mythical mind control machines or drugs)".
