Tetris Vision is something I suffered from a lot as a
kid.
It was usually brought on by a particularly heavy session of the
GameBoy classic,
Tetris, and a large dose of
caffeine.
I would lay in bed staring at the far wall, the
caffeine pumping through my body, keeping me
awake. Staring blankly, I'd envision the
tetris blocks falling from the
ceiling. I’d fit a long one down the side of the wardrobe, a square one on top of the notice board. It used to drive me
crazy. Closing my eyes didn't help either as I'd just envision the actual game, in full green and yellow
glory. Perhaps I needed
psychiatric help.
Tetris was the main culprit although I occasionally suffered from
Sonic the Hedgehog Vision too, racing across the picture rail.
