Video game after image

anyone get this? when you've played a video game all day and then you go to sleep to see the video game?

I was playing call of duty modern warefare 2 yesterday, and went to sleep that night. While falling asleep, it's like you imagine yourself playing in first person in the game, and ..except it's automatic..you don't intentionally decide to dream or even think about it..it just happens on it's own.

It was fun, maybe that is a potential way to WILD.

It's called the Tetris effect.
