I think we all are intrigued by the concept of Haunted Houses and who dwells in them. I for one find them absolutely creepy but delightfully fun. So here's your writing exercise. Create your own Haunted House. It can be a place that's only filled with ghosts, or perhaps ghouls and vampires. It can even be inhabited by humans! Where is your Haunted House? Is it in Transylvania? New York or some fantasy world? Describe your Haunted House and all who lives there or haunts there. You can make it as creepy as you'd like.
