A news report from the Daily Mail reveals that Lee Hadwin, an artist who can only create when he sleeps, is showing his first art exhibition in South London.

Lee Hadwin, 39, replicated the sleeping environment where he produces his paintings and is now displaying them at a gallery in Croydon, south London.

His condition, which has reportedly been medically proven, sees him drawing on walls, tables, clothes and discarded newspapers with various materials – from pens and crayons to paints and coal.
