If your answer is the latter, then Jayne Gackenbach would suspect youre also a hardcore gamer. Gackenbach is a psychologist at Canadas Grant MacEwan University and arguably the worlds preeminent expert on how video games can impact dreaming. In the early 1990s, her son Teace (with whom Gackenback later co-authored a book on gaming) started playing Nintendo, and Gackenbach found herself fascinated with the potential impacts of her sons new hobby. Those transformations, Gackenbach says, also offer insights into how video gaming might shape an individuals experiences in the waking world.
