You sound like my father who died about 20 months ago in an assisted living facility across town from his house.
I inherited his house and my nephew lives with me there while he looks for work. Many people, friends of my nephew who have come to visit, have seen a tall bearded man, white beard and white clothing, accompanying my nephew immediately outside the house or watching them inside the home.
My nephew shows them family photos we have framed and hanging on a wall. The visitors always identify the ghost as my dad.
He has never appeared or spoken to me, but has twice notified me with his pipe tobacco smoke to the presence of small electrical fires in the home’s walls.
Believe in ghosts? What do you think. My father certainly did not believe in them and our situation is certainly ironic.
Since my mother passed over 4 years ago I have had the same thing happen twice....and she did not live with me or die here.
I am laying on our couch in the afternoon watching tv and kind of in the zone where totally relaxed but not asleep when I clearly hear her say my name. Both times I have sat straight up and looked around when Hubby will look at me and say....what?
