Shortly after my wife's father's death, our cat, sound asleep, suddenly woke, stood up, stared at the open doorway, miaouwed, & started purring loudly, my wife was convinced that her father was standing there, there was nothing visible, a couple of nights later, I had just dropped off to sleep when I heard a voice call my name, 'Maurice', pronouncing it the french way, her father used to do this for fun, I didn't wake my wife, it would of upset her, she & her dad were very close.
