What kind of house do you live in...say's by the ocean...is it like an old plantaition or mansion type house...those are haunted alot.
Even if the house your in is just old it'll most likly be haunted.
But if they aren't fucking with you on a regular basis,I wouldn't worry about it.
People who die too young or die and leave there loved ones behind.Often stick around and then get lost or confused...otherwise...I think, if they knew better they wouldn't still be here.
