I once made the mistake of reading Lovecraft in the dark near midnight when I was the only person in the house.

I ended up turning on a couple of lights, closing the curtains, and curling up with something more... comforting. Story didn't involve curtains/windows, just the darkness of a tomb, but the curtains needed closing anyway!

(Though I can't say I ever managed to bring Lovecraft with me to the breakfast table -- yet *G*)
