"My dreams tend to be like dog dreams. I'm usually so tired that I hardly dream at all. In a way, I do think that the zone one performs in - without getting too ooga-booga about it - it's like that moment when you wake up in the morning and you're emerging from a dream state but you're not quite up. Where are you? Can you hear the birds? Or is that the traffic? It's that zone in which I perform. It’s like one foot in reality and one foot in a dream state. I spend most of my life in that state!"
