The house I grew up in was built in the 1880's and my family lived there until 2004 or so. At the time of the first experience(that I'm aware of), I was only about 3 or 4 months old and my parents were in the middle of a kitchen remodel. My dad says he woke up in the middle of the night from a dead sleep and had an overwhelming sensation that someone was in the house. So he grabbed his .357 from his night stand and took our lab and did a perimeter check of the house. Nothing was out of place and everything seemed to be in order. But our dog would not go into our basement. My dad tried pushing him down but it still wouldn't budge. So my dad picked him up and carried him down and soon as he put him down he ran back up the stairs. SO my dad cleared the basement by himself. After realizing everything was fine, he grabbed a drink and decided to go back to bed. As my dad was walking back up the stairs to the second story, he looked up and saw the figure of an elderly man standing at the top of the stairs looking at him. My dad said he was close enough where he tried to grab the figure thinking it was an intruder but it simply vanished. A few weeks after that, my dad had another experience. Again he woke up and felt a presence that had the hairs on his neck standing up. He rolled over and looked through the doorway and saw the same figure staring at him from the hallway. My went to reach for his .357 and when he looked back the figure was gone. He checked the house out for an signs of a break in and could not find anything.
My dad never told my mom about what he had been seeing until my mom had an experience for herself. My dad was gone on a business in Kentucky and she was home alone with me. She woke up in the middle of the night and felt something heavy on the end of the bed. She looked up and saw a figure fitting the same description sitting on the bed looking at her. She quickly turned on the light and the figure was nowhere to be seen. She called my dad panic stricken around 3 in the morning and told him what she had saw. He played it off as a dream and there was nothing to be afraid of. After my dad returned, he told her what he had seen.
We never did figure out what the figure was. My parents have two theories on who the figure might be. One is that it is the original owner of the house not pleased with his house being worked on and the other theory is the figure being my grandfather, who passed away before I was born, checking on his son's first child. After the work was completed the figure was never seen again but every once and awhile you get the feeling like you were being watched. Especially in the basement.
The house is now abandoned and condemned. The local dump bought the house and tried renting the property but had trouble keeping tenants. The next door neighbor who I still deer hunt with said one group of renters said the house was haunted. One winter they did not winterize the house while it was empty and the pipes burst and the basement filled with water. Evidently water was coming out of the basement windows. Now the house is filled with mold and is scheduled to be demolished soon.
