A 23-year-old man claims he is stuck in a real life Groundhog Day - in a bizarre case being investigated by Sheffield Hallam University.
The victim is experiencing a severe case of deja vu, and feels like he is ‘trapped in a time loop’, according to psychologist Christine Wells.
The sufferer had to drop out of university and has even stopped watching TV, listening to the radio or reading newspapers or magazines - as he believes he has seen it all before.
He was then tormented by further attacks when he went abroad to one of his favourite resorts to try to relax.
While on the holiday he reported feeling he had ‘become trapped in a time loop’.
The case is believed to be the first known example of a person experiencing persistent deja vu stemming from anxiety, rather than an underlying neurological disorder such as epilepsy.
Dr Wells said: “Our subject complained that it felt like he was actually retrieving previous experiences from memory, not just finding them familiar.”
She believes the patient could be trapped in a vicious circle in which deja vu experiences make him feel more anxious, which in turn trigger further similar feelings.
