My sister's house has a ghost. I am not saying her house is "haunted" it just has a ghost. We think it is a little boy.
We discovered the little bugger about 15 years ago. My nephew's were 4 and 3. My niece was an infant. The 1st indication that something was going on was, not long after they moved in, my 4 year old nephew got a "friend". At first, we thought it was an imaginary friend, my nephew had full converstions. Asked questions, waited for a response, and even replied to questions. His friend's name was "Jimmy'.
Around this time, a few months later, my BIL had to get up and go to the bathroom in the middle of the night. Their room was in the front of the house, at the end of the hallway. Just outside his bedroom, on the right was the baby's bedroom, which had an internal door to the next bedroom. The boys room. when he came back from the bathroom, he went in the baby's room to make sure she still had her covers on. As he was tucking her in, out of his perephrial vision, he saw a little boy go into the other room. He thought it may have been the 3 yr. So, he goes in to tuck him in, and sees an empty bed. it is then he realizes, BOTH boys were asleep in his bed. He knew he saw a little boy. He went and sat on his bed, woke my sister up, and told her to feel his arms. The hairs on his arms were standing straight up.
About a year later, my sister was doing some ironing in her bedroom. She saw someone standing in the corner behind her, and thought it was one of the kids. She continued ironing, and without turning around asked if they were just going to stand there or did they want to say something. No response. when she turned around, the room was empty.
The real proof was when I moved into the attic. For about a month, every night at midnight, the attic door would open and close. I am really surprised it did not freak me out. For some reason it didn't.
