Heh, I don't write fanfic, though I tend to think up stories with my OC's(that is. non-fandom OC's) and such before I go to sleep. I also try to think of funny stuff if I've seen something scary before going to sleep, so I won't lie awake half the night.

...of course, I should probably not read/look at scary stuff before going to bed, since I scare so easily, but eh, I'm weird like that.
