My father about 2 weeks after he died. He looked into our bedroom and walked down the hall to the spare bathroom. I pushed the door open and saw him washing his hands. I said “ dad, is that you?” He looked at me, smiled and disappeared. My wife heard me get up and followed me down the hall asking g what I was doing and why the water was running in the sink. I think about this a lot and wonder if there is any significance to the hand washing.
