I lived in a home in NJ that was built on land used during the revolutionary war. Many things were seen and heard by every family member. One evening in 2017 I sat in the hall way with my children folding clothes. I saw the hatman out of the corner of my left eye standing in my bedroom door way. When I turned my head to look at it straightforward I sensed that it realized I saw it(and I wasnt supposed to)it literally just vanished. I hadn’t taken benadryl, any other drugs or alcohol. It creeped me out.
