At the home I was born in, as a child we lived with my grandparents. When my parents were married, my grandparents gifted them the house for their wedding and moved out. My mother grew up in the house and said that all her life she had an eerie feeling in the house. I have no idea when the house was built or anything about the owners before my family.
When my mother was still engaged to my father, she opened their bedroom door one night to go to the bathroom, and standing in the hall in front of the door was an image of herself as a young girl. The image reacted to her being there, turned and disappeared down the hall. My mother said that she recognized the dress as one she had worn around that age.
A few years later, my little brother is an infant. My mom and aunt were outside on the back deck, having a smoke and a drink together when my mom heard my brother crying from the baby monitor. She went to get up and my aunt told her that she would get him, she had to use the bathroom anyway. So she went inside and my mom listened, my brother went quiet and my aunt came back outside. She asked my mom if she had gone inside to take care of my brother anyway, to which she said she hadn't. My aunt told her that she had heard her walking down the hall mumbling about "the godd**n baby is crying again".
And, finally, this one spans over the whole time that I lived in that house after my grandparents had moved out. My grandmother was a frequent visitor, but every time she would leave the house, every smoke alarm would go off at the same exact time precisely five minutes after she closed the door behind herself. We tried everything we could from disconnecting them to taking out the batteries, but it always happened.
