It was the Christmas eve exactly one year after my grandpa died I was about 3 at the time, when we all went to bed it was snowing pretty hard out so we were expecting to have a very white Christmas this year.
About 12:00 that night the door bell rang. This might not sound weird to you but the crazy thing is that the door bell has been disconnected for over 2 years.
My grandma went to answer the door and there was no one there. Well there were no foot prints in the snow either.
About a half hour later the door bell rang again. Once again my grandma opened the door only to find nothing no foot prints or anything.
This went on for about another hour. About 2:00 I got up to go to the bathroom and I saw my grandpa standing in front of the Christmas tree and he asked me why we didn't let him in when he rang the bell. Now needless to say I was really scared so I took off running and jumped back into bed.
When I woke up the next morning there was a giant wet spot in the carpet where my grandpa was standing.
Its happened every Christmas since then. Only I'm no longer scared of him. There have been a few other meetings with dead relatives but they are another story.
