My Mother came to me in a dream (well it must have been a dream!) the night after my father died. He'd been an utter bastard to her for over 60 years so when she died three months before him my thought was that at least she was away from him at long last, however the guilt must have been too much and off he went to try to follow her
My over-riding thought was that he'd gone off to spite her and ruin her peace.
I did not sleep at all that first night maybe worrying about him rocking-up there to ruin everything for her then make her miserable like he always did, but the second night I seem to recall waking -up (whether I did or not is questionable) BUT there was Mother in her nurse's uniform wearing her white sensible shoes and everything standing beside my bed with a big smile on her face. "Don't worry about him ruining my peace" she said rather joyfully, adding "THEY wouldn't let him in!" I knew then that she would be enjoying the afterlife free of that man at last and back with her parents who hated him for very good reasons
I'm delighted that "They" wouldn't let him in
