My Great-Grandfather's Ghost

This is the only personal ghost story I have, and it's not even really "mine", but I thought I'd share it anyway.

My great-grandfather died of cancer when he was in his late 80s. He spent the last few months of his life in a hospital bed in my grandparents' living room. I was about eight years old at the time and my memories of it are a little bit hazy; this was about 25 years ago.

My grandfather was an incredibly practical man who I would never imagine making up stories or even seeing a ghost at all. But apparently, the day of my great-grandfather's funeral, my grandfather walked into the living room afterward and saw my great-grandfather standing in the middle of the room. He looked the way he had as a young man and was wearing a suit. As my grandfather watched in shock, he turned and walked up the stairs and disappeared.

Of course, he might have imagined it all; I'm sure having his father-in-law dying in his house had been a pretty stressful time for him. But it's an interesting story nonetheless.
