The Null Device
A study has shown that people who grew up watching black and white television dream in black and white, whilst people who grew up with colour television dream in colour:
Research from 1915 through to the 1950s suggested that the vast majority of dreams are in black and white but the tide turned in the sixties, and later results suggested that up to 83 per cent of dreams contain some colour.
Only 4.4 per cent of the under-25s' dreams were black and white. The over-55s who had had access to colour TV and film during their childhood also reported a very low proportion of just 7.3 per cent. But the over-55s who had only had access to black-and-white media reported dreaming in black and white roughly a quarter of the time.It isn't clear what sorts of dreams people who grew up without television have; whether they're less visual and more verbal, more three-dimensional, or just less spectacular.
