Gamers who play for hours are prone to hallucinations and seeing distorted versions of reality, according to a new study.

Respondents reported seeing “distorted versions of real world surroundings” and “misinterpreted real life objects” after they had stopped playing. Others said that game menus appear in front of their eyes during conversations.

The study, compiled from responses by 483 forum users, explored the concept of “game transfer phenomena” – experiences where players’ perceptions, cognitions and behaviours are influenced by images seen while gaming.

Among the categories of experience recorded were “multisensorial”, for example hearing video game music, and “retinal sensations” when players see “game elements intermittently or episodically in the back of the eyelids”.

Some gamers told scientists at Nottingham Trent University’s International Gaming Research Unit that they see “coloured images” and “heads up displays” while driving on the motorway.
