I have never shared this with anyone until now (God's timing).  I was probably around 8 years old (1968; "now you know my age") when I had my first real demonic experience

My three siblings plus our parents were living on the 2nd floor of the house our grandparents (our mother's side) built (they took a ship from Sicily Italy to New Jersey USA in the early 1900s).  My grandparents built the house in the early 50's - 1952? (70 years ago) in New Brunswick NJ (Franklin Township)
