This experiment aimed to create a laboratory analogue of déjà vu. During hypnosis, one group of high hypnotizables completed a puzzle game and then received a posthypnotic amnesia suggestion to forget the game (PHA condition).

After hypnosis, all participants were given the game and described their reactions to it. Whereas 83% of participants in both

An EAT inquiry revealed that they experienced sensory fascination and confusion about the source of familiarity, akin to everyday déjà vu. These findings highlight the value of using hypnosis as a laboratory analogue of déjà vu and provide a framework for investigating clinical manifestations of this phenomenon.
