In my house, you could open certain doors quickly and other doors elsewhere would close. The same thing would happen when the heat pump came on. Also, if you stepped on the pedals of my piano, some of the keys would ever-so-slightly move on their own.
My best friend and I NEEDED to get his tag-along little brother to leave us alone, so we set everything up carefully, and with a few automatically closing doors and piano keys that moved on their own, Nicky was convinced my house was haunted.
And when we played over at THEIR house? I came over with a ceramic pot and we told Nicky it had the ghost in it.
He never bothered us much.
