Colour or black-and-white?

Plenty of room for doubt, controversy and endless, stultifying recounting of each other's dreams in this story about a researcher who has concluded that whether you dream in colour or black-and-white depends on which type of television you watched when you were a child.

But what I find most interesting is the fact that no one seems to have asked the most obvious questions here: what were people's dreams like in the days before television? Did Elizabethans dream in blank verse? If, as it appears, watching television changes the way our subconscious operates, shouldn't we be backing away slowly with our free hands scrabbling for the remote?
