Mindbending
From Tardis Wiki, the free Doctor Who reference
Mindbending was a form of psychic wrestling played by Time Lords. Usually it was only a game, but it could end in deathlock. The competitors placed their heads against the mindbending device and the process began. It involved mental warfare hence, mindbending. The Fourth Doctor and Morbius entered a mindbending contest on the planet Karn. The Doctor won, though nearly at the cost of his own life. (DW: The Brain of Morbius)
