Gamers have control over their dreams

A story in Slashdot says gamers have control over their dreams. I have control over my dreams more often than not, does that mean I'm a gamer? I don't play video games that often, not recently that is. The concept is cool. Maybe you can teach people to have better control over their dreams based on research on how gamers do it, so you can cure people of nasty nightmares.
