Day dreams are easier - you wake up and you have the energy and time to write it down. All the papers I am reading I send to the iPad. I got reading, then gently closed the iPad and slept. I filed and sorted papers in the dream. If this sounds like a nightmare then I should add that they were each like a highly starched duvet. The 'clarity' came later walking the dog. Doing something else and working with dreams are valid techniques by the way.
