As I've mentioned before I'm usually at my most creative when I'm at my most tired. I really did recently have a time when I was trying to lay back and get to sleep but my mind wouldn't turn off and I kept breaking out the notepad. The main reason for this though was that I was trying to solve some problems with my book, and when you're just relaxing, doing nothing (like how people tend to try to get to sleep) your brain is going a mile a minute. When you're not really do anything your brain is working hard in the background solving problems. It's why if you can't solve a problem the answer will randomly come to you when you're laid in bed. The only problem with this is that it's usually forgotten by the time you wake up.
But as well as being to do with problem solving, it is also creativity with me. I've managed to think up pieces of dialogue for stories, even occasionally a full poem while trying to get some sleep. But I seriously hate sleep. There's just something about being that vulnerable that I just do not like. I get "enough" sleep. I appreciate that you need sleep really. This does not mean I have to enjoy the idea of sleep. It takes me so long to get to sleep because I fight it so much. The more tired I am the less I want to sleep. As well as being more creative, I'm also more active while tired. Or at least I have the potential to be. I want to do anything but sleep.
Sometimes I wonder if my aversion to sleeping is deeper than simply not wanting to be vulnerable, who knows? I really just don't like the idea of being completely unprotected.
Still, I now take my phone to bed with me (I use it as an MP3 player, I'm not just that weird. I never call or text anyone or receive them. I'm so ronery.) and I use the memopad on that, so at least now when my brain refuses to shut down, I have something I can write with should I get an idea that just has to be preserved.
