Using all the senses - sight, sound, smell, taste, touch - and specific detail, describe a haunted house.
This exercise is actually right up my alley at this point in my life. I've been watching a lot of supernatural television such as Ghost Whisperer (starring Jennifer Love Hewitt), Angel (starring David Boreanaz), and various other creep-tastic shows, so I'm figuring that I've learned to write fiction like this through osmosis... Or maybe that's just wishful thinking?
I don't know what it is, though, but there is just something fascinating about ghosts and demons and so on. Maybe it's the fear of the unknown. You know, whatever is just beyond that realm of human comprehension. Where do we end up when we die? Is it possible to get stuck in between life and afterlife, doomed to roam unnoticed until your "unfinished business" is, in fact, completed? It's a really interesting concept, and it's one that has haunted - pun totally intended - people for ages.
But anyways, on to the exercise...
