If you are looking at a house and feel compelled to ask, "Did anyone die here?" They probably did. Whether the owner/realtor knows about it or lies about it, if you asked it is because *you felt something there*. Every time I have felt the urge to ask, yes, somebody died there.
Our previous home that we rented, the owner lied. I knew she lied. I walked the dog through the house and he was OK, so we went ahead and rented there. We hadn't been there more than a couple months when Charlie was in the other room and I was reading to him an article in the paper. I felt him come up behind me and lean on the chair, one hand on either side of me, reading over my shoulder...at least I thought it was him until he said something from the other room. I found out from a neighbor that the man that lived there died in our spare room--the room where the closet would not stay closed. There was something else there, not the friendly spirit of the late owner, but something down in the former
michigan basement (somebody had covered the dirt floor with about a 1/2 inch of cement) that had a dirt-floored
cistern and a little room with a safe built into the wall. There was something down there that had nothing to do with ghosts...
I asked about this house, too. However, there is nothing here I fear. Mr. Gee, the man who built this house, does not disturb me at all with his presence. There is also a cat here. I didn't feel the urge to walk Jack through here. Probably because there is nothing ominous.
A friend lived in an apartment, underground, that was haunted. If her son's bed was on the wall that shared her bedroom, he would wake in the night screaming. They moved his bed to the opposite side of the room and he was fine after that. She made her husband sleep on the side of the bed closest to that wall. One night while he was gone I slept over and had a very disturbing nightmare about a tall, bearded man wearing gloves and high hat. He wrapped his hands around my throat and I woke up gasping. When she asked what I had dreamed, we went back and forth instead of me telling the whole dream--because the few times she had slept in that spot, she had had the exact same dream! I'm telling you this because it's not just houses that get haunted.
For what it's worth, if you can, walk an animal through a home before buying, I recommend it. Even though that didn't make me completely informed, I was still satisfied that the main living area was okay.
