My grand parents moved in the rock house in 1980. Space was very limited for a family with 5 kids and only a 3 bedroom house. At first, when they moved in, everything seemed pretty normal, but after a few months they started hearing noises, like footsteps in the hallway when there would be no one there. My grandmother kept two small dogs in the house and she began to notice that every time something strange would happen, they would hide in the bathroom. One night, my dad and his 3 sisters were coming back home from the movies. When they pulled up to the house, they could see through the window what appeared to be my grandpa going into the bathroom. My dad waited outside of the bathroom for a few minutes, waiting for my grandpa to come out. After waiting for a while, he got worried and opened the door and didn't see anyone.
A few months later, another strange thing occurred. My aunt was sleep walking, which she did a lot, often she would fall and accidentally hurt herself. My dad hadn't fallen asleep and heard her moving around downstairs. So he went down stairs and tried to find her. When he did, she was walking towards the bathroom and there was a man standing in front of her, only a few feet away. He was wearing overalls and and a long white beard that came a few inches below his chin. My aunt just kept walking and walked completely through him! After that he disappeared.
When my grandparents moved out 5 years later, he was still making noises and appearing often. Over the years, only a few people have lived in that house, most only stay for a few years and leave it empty for a little while.
Thanks for letting me share this story.
