Does anyone know of any artists who have written songs or ideas from dreams or semi-conscious states?

So far I have Paul McCartney waking up to hearing 'Yesterday' in his head, and Boards Of Canada's Marcus Eoin writing 'Gyroscope' almost exactly as he heard it from a dream.

I also read that Fever Ray wrote her album half-asleep, as did Mike Patton when he wrote the lyrics to 'Caffeine' during a sleep deprivation experiment, although they're a bit tenuous...
