You know my paternal grandfather had an experience with a ghost once. I guess. It was the anniversary of his beloved wife's death. She died in 1973, and he lived well into 1994. But he told her spirit. If you are here, if your presence is with me in my house still, at some exact time, knock three times. And. At that exact time, though he was home alone, in his bedroom he heard three knocks! And it scared the living sh*t out of him, he told us. So he sprinkled a little holy water everywhere, to be safe. It's good you know, to have holy water handy, for just such an occasion. You can't hold the aspergillum vertically as you sprinkle. That would an exorcism. But you can hold the aspergillum (he used an old baby food jar) horizontally, to sprinkle it lightly on the floor.
Why would he ask a spirit to let him know they wre there amd then be scared?? I have asked spirits to do stuff like that but they dont ever
