This is from an interview with musician Richard D. James (more commonly known under his alias of Aphex Twin), I think it's relevant to the topic -

TO BE THIS (OVER) PRODUCTIVE is closer to an affliction than a gift. A week before our interview, James got stranded at his parents’ home in Wales (his car broke down); being separated from his studio nearly drives him mad. This need to unloose the flood of ideas is one reason why he sleeps such a famously small amount: two or three hours a night. He tells me he once went five weeks without a wink. Come off it, I say, sleep-deprivation is a form of torture, a way of inducing mental breakdown prior to brainwashing. Why does he do it? And how?
"When I was little, I decided sleep was a waste of your life. If you lived to be 100, but you didn't sleep, it'd be like living to 200. But , originally, it wasn't for more time to make music, it was just that I thought sleep was a bit of a con. I'd always been able to get away with four hours a night, but I tried to narrow it down to two. And you do get used to it. I reckon it'd take you three weeks to whittle down from eight hours to two. You should try it, it's wicked."
My theory is that sleep deprivation has everything to do with the eerie, spaced-out aura of Aphex's music. Neurologists say that humans have an in-built need to dream. Which is why you feel ‘unreal’ if you've stayed up all night or are jet-lagged: the brain is trying to dream while you're still conscious.
"It gets very strange when I don't sleep for a long time. Cos it's not that I'm actually that good at staying awake. I can only do it if I'm making music. If I watch TV during a period of going without sleep for three days, I always fall asleep immediately. But it's f*****g excellent, not sleeping, you really should try it. It’s sort of nice and not-nice at the same time. Your mind starts getting scatty, like you’re senile. You do unpredictable things, like making tea but pouring it in a cereal bowl."
