There are weird things happening so, who died in my home?

I don't think we would be able to figure that out for you. I think the best option would be some local research at your local library, office of public records, or neighbour/local business owner. If you have a REALLY old house then this could take a while, but you also need to look at your house to make sure that there isn't a logical explanation for what is occurring. What is occurring? There is a lot that can be explained by the house and it's construction, but with that being said there is a lot that defies explanation. Sadly the burden of this will lay mostly on you to figure out.
