I grew up in a 200 year old farm house near Saratoga,NY that I swear was haunted. The house was part of the underground railroad back in the day. It had all kinds of secret entrances, rooms, trap doors, hidden rooms in the basement (which had a dirt floor), etc.
Half the place was basically condemned. It's a 15 room house, but we only used about 6 rooms on 3/4's of the first floor. My bedroom just happened to be on the edge of the old condemned part. I had to leave a set off huge double doors open to that room because the wood stove that provided my heat was in there.
I heard many strange and and creepy things come from that room and the hallway behind it which lead up stairs. People talking, breathing, walking around, stuff rolling down the stairs... all kinds of stuff. I never saw anything but I didn't need too. The sounds were scary enough.
Some of the walls had holes in them which exposed old kids clothes, kids shoes, old fabric, newspapers, etc that were packed in for insulation in the early years. My step sister told me that there were people buried in the walls which freaked me out because of all the clothes you could see stuffed in the walls.
The house was also used during the battle of Saratoga for soldiers who were in the battle. A lot of wounded soldiers stayed and probably died there. If there's any ghosts I bet they are from that time period. I always though the sounds I heard from the basement at night were the ghosts of dead soldiers making noise.
On another note, one Historian in the area said most likely George Washington spent some time there which is kind of cool.
The secret passages were neat! You could go into a closet and come out on the complete other side of the house. The trap doors always freaked me out though because you could feel where they were under the carpet and I knew they led to the basement rooms.
I haven't been there in like 20 years. I'd like to go back and see if it's still as creepy as I remember. It appears to be in the same condition.
Just kind of rambling here, but this thread got me thinking about the old place.
Here's a picture I took of it when I was in 6th grade photography class back in '86.
