Sleep meditation tones for creative minds that need half an hour to quieten down after a day of ideas. This gentle sleep meditation is built around soft, steady tones and runs for 30 minutes. Play it at a low volume while you write, sketch or tinker, or as you wind down and let the day's ideas settle before bed. A steady sound in the background makes it easier to switch off from emails and notifications. (A relaxation aid, not a medical treatment.)
