^^ Agreed about the FA loop part, and that's good advice about the sleep mask as well.

I hadn't thought about it (I suppose I should have ), but I use a sleep mask specifically because light is the enemy of sleep, and it tends to find a way to interrupt my dreams if not kept out. By nullifying light with a sleep mask you do indeed remove a major obstacle to steady lucidity and, perhaps, you are also discouraging FA's. I don't use it as such, but yeah, a sleep mask would also be an excellent source for RC's as well!
