I haven't actually seen the ghost myself but my family members have told me about her many times. (You know how relatives can be :)
My mom was sleeping one night and woke abruptly for no reason at all. She saw a girl standing in the doorway in a blue dress that looked amazingly like my older sister at the time. My mom, confused as to why my sister would be up at this time at night, told her to go back to bed. When she did the girl vanished into thin air.
A little while later my Aunt was sleeping over and was sleeping on the couch. Again my aunt woke up for no reason. There was a girl just standing there then she vanished. Now I'm not sure if this girl was just my sisters spirit going for a stroll or a actual ghost that haunts my old house.
