UFO and Aliens
Most people who report being abducted report having their minds wiped, with memories recovered spontaneously, or through therapeutic engagement, such as hypnosis. This is so routinely discussed within UFO literature, one might assume the trope for artifacts like the Neuralizer in Men in Black might originate from UFO enthusiast. See, we enthusiasts did something good! Wiping memory was also used in an episode of Star Trek: The Next Generation, “Pen Pals,” after Data broke the Prime Directive and rescued a child from imminent death.
