I got home from therapy, had some breakfast, and then needed a nap.
I would never in my wildest imagination consider The Phantom of the Opera, a novel I've loved since a kid, a supernatural book. Lot of gothic horror trappings, but, like Paul Gallico's Too Many Ghosts and the Bob Hope film The Ghost Breakers, there's not a real ghost in sight.
I would add to my list of books:
A Christmas Carol
Ghost Story
The Woman In Black
Something Wicked This Way Comes
And films:
The Woman In Black (BBC version, not the Radcliffe film)
The Blair Witch Project
The Legend of Sleepy Hollow
The Canterville Ghost
