Interesting, but it doesn't gel with my experience. My parents had such disdain for the box that we kept a black and white T.V. until it expired in the late eighties. Not only do I dream in colour but I have 178 channels of absolute crap to chose from.
I've had dreams in unix and Emacs.
I've dreamt of Tetris...
is 60 people really a statistically significant sample size?
