 This will be the shortest video ever. Someone has emailed me saying, should I have the lights on or off if I want to lose a dream? When you go to sleep you should have the lights off because when you have the lights on it stops your body producing melatonin which makes you tired and helps you fall asleep. So when the lights are off you produce more melatonin and you fall asleep faster. If you fall asleep faster you're more likely to dream you're more likely to lose a dream. Done.
