"Jesus Christ, Joe. You've been playing way too much Skyrim
, haven't you?"
A character starts to be unable to tell the difference between fiction and reality. Often it's thinking a TV show is real, or thinking one is actually in the show.
This trope can either be Played for Laughs
or Played for Drama
. The dramatic versions can often come with a moral about not watching too many shows or not thinking stuff in shows is safe to do
A Super Trope
to But I Play One on TV
(can't tell an actor from the role played).
A Sister Trope
to Daydream Believer
(thinking the fiction is real but separate from our reality), Lost in Character
Compare The Tetris Effect
(but people can tell they aren't in a game; they just see things as a game), Longing for Fictionland
(knowing it's not real, but really wanting it to be), Loony Fan
