So sorry for your loss new boy.
The law of averages... A few weeks ago, out of no where, I dreamt that an old acquaintance had died and I was at the funeral home comforting her 2 sons and grandchildren. There is a poster here who knows her and goes to the same Hall. He assured me in a private message recently, that she is alive and well.
I don't doubt your OP at all. I have heard of similar stories as yours, happening, as in close friends, loved ones, being visited after death to say good bye.
How do you feel about it?
