I've been kind of in the same boat as a lot of you with the dead/comatose muse thing. Mine seems to be slowly waking up. I blame it mostly on being busy and having too many other things to do and too much on my mind to focus on writing.
I am slowly starting to get back into the swing of things by writing some parts for my collaborations, but I haven't written anything on any of my own projects since I finished Secrets of the Heart in August. I had to force myself to finish a part for Undead before Halloween, but that did seem to wake up my muse because I have done some writing on 00Carter now too. Like Lore said, sometimes you do just have to force it to an extent, or it will never happen.
