Ghosts Playing Cards

Well the story's not about me its about my grandma. It was 1974 and she was at here sisters house and it was about 12:00 at night she woke up to the sound of people playing cards.So she walked toward the kitchen and she saw people playing cards and tried to go back to sleep.When she couldn't take it any more she went to her sister and told her to tell here friends to stop playing then she said what friends and my grandma said the ones playing cads down stairs in the kitchen.Then my grandma took her down stairs but there was no one there.

I wasn't alive to see it but my mom did
