Is there a comic book or book based on the topic 'sleep'?

I want to read something both enjoyable and informative. Only book I managed to find is "The Empire of Sleep" by Henri Frederic Blanc. I really enjoyed it because I love sleeping and very curious about the topic.

by Raymond Chandler. He was a mystery writer so you can probably guess what The Big Sleep is.

Sandman Sleep of Reason by John Ney Rieber is a brilliant comic book. Although it is as much socio-political as it is about sleep
