I always dreamed of having an old historic building to convert into a Bed and Breakfast, perhaps have a 10 o'clock scary story telling in front of the fireplace while sipping brandy with the guests.
There is something interesting about having guests in a haunted location for the night. When I was growing up, it seemed that weirdness came out in droves during the night for visitors.
One time, my brother's friend awakened to something often encountered in the house, a blue mist forming overhead and icy cold temperature drop. Another friend was playing hide and seek with me, hid behind a berm and a ghost man in a war uniform on horseback leaped over her, disappearing in mid air. Another time, a visitor went upstairs to check on her baby and screamed. She saw the dark shadow figure in the hallway.
In Missouri, there is a place called the Haunted Castle House and it has been turned into a bed and breakfast.

The place allows for ghost investigation teams, has tours, and haunted rooms. And, once every month they have a fun event (I've done one before and they are fun) - a murder mystery act.
For all my Midwestern buddies or those on road trips trekking through this region, you might want to put this spot high on your list.
