This is counterproductive

I have a headache, and I've been out of it the last couple days. The reason, I think, is because I have not written fiction in a long time. Not writing fiction for too long (a couple weeks) leads to me having more and more dreams, which makes it harder and harder for me to wake up, and makes me feel like I haven't rested during the day. My brain is simply exhausted. I need to write fiction before the dreams get worse (like, dreams about sex with relatives), but I am out of it and have a headache because of the dreams, which makes it really hard to write. Argh.
