Uh, so, in my galaxy I'm something called a Jedi. I can use powers to help you quiet your mind for a bit. Even sleep. I just can't use it on myself. I could ask Anakin to help me sleep, but then I'd have to explain the nightmares.
Meditating has been a part of my life for as long as I can remember. It is how I calm my mind, normally. And yeah, I'll probably nap at some point.
