The Second Doctor uses hypnosis on a Zagbor to help free the human race. (COMIC: The Zombies)

Hypnosis, sometimes known as hypnotism or mind control, was the ability to place others into a state in which they would obey the commands of the hypnotist or believe what the hypnotist told them. Some forms of hypnosis were stronger than others. Memory erasure or alteration also could be accomplished hypnotically.

The Doctor and hypnosis[]

The Doctor occasionally practised hypnosis. Time Lord DNA included a psychic empathy field, indicating that all Time Lords may have been capable of hypnosis. (AUDIO: The Oseidon Adventure)

To break the mind control by the artificial intelligence WOTAN, the First Doctor used it on his companion Dodo Chaplet, leaving her asleep for 48 hours and forgetful of the accident. (TV: The War Machines)

In Det-Sen Monastery in Tibet, the Second Doctor repeatedly counteracted the mind control by the Intelligence over humans, such as monks and his companion Victoria; in the second instance, he counter-hypnotised her in order to catch information about their enemy. (TV: The Abominable Snowmen)

BOSS unsuccessfully uses its conditioning on the Third Doctor with increased power. (TV: The Green Death)

Even the Third Doctor proved to be able to break a state of hypnosis caused by others: on Jo Grant manipulated by the Master, through a verbal technique (TV: Terror of the Autons) or on the scientists kidnapped by the Sontaran Linx, with the help of an intermittent light. (TV: The Time Warrior) He could also resist forms of hypnosis which would defeat weaker-minded individuals, such as BOSS's conditioning at its strongest power frequency. (TV: The Green Death)

The Fourth Doctor hypnotised Sarah-Jane Smith in order to reduce her oxygen requirements inside a decompression chamber (TV: Terror of the Zygons) and to recover information about the entity that had possessed her through a Kastrian ring (TV: The Hand of Fear) simply by laying his hands on her temples. On Pluto, he once hypnotised one of the Company's guards in this way — and accidentally hypnotised a watching Leela, as well. (TV: The Sun Makers) On Ribos, instead, the Fourth Doctor used a fob watch to hypnotise a guard of a relic room. (TV: The Ribos Operation)

The Twelfth Doctor made Rupert Pink sleep and scrambled his memory about their rendezvous, by pressing his fingers against his temples. (TV: Listen) In order to go undercover as Coal Hill School's caretaker to stop the Skovox Blitzer, the Doctor hypnotised the position's occupant, Atif Basra, into believing he had the flu, as well as a flying car and three wives. When Rupert, by then known as Danny, met the Doctor as an adult and discovered his existence, his girlfriend Clara Oswald asked the Doctor not to meddle with his mind. (TV: The Caretaker)

The Master and hypnosis[]

As a means to his ends, the Master frequently used hypnosis to have people perform tasks on his behalf. He most commonly did this through suggestion, uttering the phrase "I am the Master and you will obey me". However, his success rate at hypnosis was sometimes poor, owing to potential victims' stronger wills. (TV: Terror of the Autons)

While working under the alias of Professor Thascalos at the Newton Institute, the Master hypnotised its director, Charles Percival; he later commented that it had been a long time since he came across a hypnotic subject as good as Percival.

(TV: The Dalek Invasion of Earth) Davros showed to have at his disposal a device able to put both humanoids and Daleks under his control by skin contact. It flashed with a green light. (TV: Resurrection of the Daleks)
