Hypnosis is a mental state in which the conscious mind is relaxed and the subconscious mind becomes more active. Often, people under hypnosis are able to recall memories and feelings through their subconscious mind that they cannot otherwise access through the conscious mind. In some cases, those who are hypnotized may even recall memories from a past life. The practice of putting someone under hypnosis can be tricky and is usually only conducted by a trained medical physician, a psychiatrist or in some cases, an occultist. Some dabblers of magic are also able to render people into a hypnotic state. Those under hypnosis are vulnerable to post-hypnotic suggestion, in which an individual may plant ideas into their subconscious mind to be carried out by the conscious mind at a later date.
An example of hypnosis can be found in the DC Comics character Ophidian, who is a member of the mutant sub-race known as the Un-Men. Ophidian once used his powers of mesmerism against the Swamp Thing, forcing him to remain stationary in a single spot, thus allowing the rest of the Un-Men the chance to capture him.
