I couldn't sleep.
The writer never really sleeps. I think we write in our sleep. Possibly, and I'm sure I'm right on this, the creative mind never really relaxes. This can be said of inventors on down through the chain of creative people, musicians, writers, artists, etc.
So, when I'm on to something that is a scene that has just burst into my head, and I'm thinking "yeah, that might be something. Now how will it go?" and I go to bed, I may not fall asleep right away, or maybe I do. But at some point I wake up and then the thought is there of this scene. I'll have the characters in my mind talking, going through motions. I see them just like a motion picture. I know all writers must have this trouble sleeping. Or, if they don't they wake up with it in their heads. I do this too.
A lost of times I have a problem to solve. It seems to be an unsolvable one, but if I just allow it to germinate in my head while I sleep, I wake up with this solution and it's as though I didn't even have to break a sweat. Well, I didn't.
So, when it's not a full moon, or even when it is, if I can't sleep, that's not good because I do have a job to go to. I drive transit bus. I've had two bad days--feeling crappy because of one lousy night. Last night I took two sleeping aides and I know I shouldn't have, and today I felt like crap all day.
Tonight I'm just going to go to bed and SLEEP.
