I've heard a 'handprints ghost story' about a school. There were handprints that would appear on the windows of an old classroom at night. Turns out, it was said to be a student who had died in a fire in that very classroom long ago. The handprints were thought to be the ghost of the student trying to get back into the place they loved. It was really spooky because the janitor would often see the handprints in the early morning and they would disappear as the sun rose.
There was a story about a ship. Sailors reported seeing handprints on the deck. These handprints were not of any living crew member. It was part of a ghost story that a sailor who had been thrown overboard during a storm many years ago was now haunting the ship. The handprints were seen as a sign of his presence, and whenever they appeared, there would be strange noises and an eerie feeling on the ship.
