Do you need complete silence? complete darkness? Do you like the electronic hum of the radio or the telly to lull you to sleep?
I genuinely find listening to stuff like David Icke/Ancient Aliens/Doomsday Preppers helps me to nod off. It's just that some of that stuff is so unbelievable in parts that it's almost like being read a story at bedtime. Radio phone-in shows are a one-way ticket to snoozeville too. Definitely find it more difficult to get some shuteye in total silence.
