Thought it was sleepy hollow? Oh, well. I mistyped it in the title, and I'll have to remember to fix that.
"all hallows eve"--in that "hallows" means "souls". Deathly souls? Sounds like...either Dementors, or...I like your idea about the Veil. Of course, I just want to see Sirius again. How/why did it disturb you?
Thanks for the link. The hyperness is beginning to kick in, unfortunately, but I needed an outlet for my brain and that was it.
