A student in a dorm once woke up in the middle of the night to see a white figure floating above his roommate's bed. He was so scared that he couldn't move or make a sound. When he finally managed to turn on the light, the figure was gone and his roommate was still sound asleep.

In a particular mine, there were reports of a ghostly miner who would push people. Workers would suddenly feel a shove when they were alone in the tunnels. It was thought to be the angry spirit of a miner who had been mistreated during his life. The atmosphere in that mine was always filled with fear, and many miners refused to work there in the end.

The scariest I know is of a pup in an old, abandoned house. A group of kids exploring the house heard the sound of a pup crying. When they followed the sound, they saw a shadowy figure of a pup. But when they got closer, it disappeared. They later learned that a pup had died in that house decades ago and its spirit still haunts the place. It's terrifying because it makes you wonder what else might be in that abandoned house.

One of the scariest is the story of the hound of the moors. It's a large, black dog with glowing red eyes. It is said to roam the moors at night, and if you hear its howl, it's a sign of impending doom. People have reported seeing it chasing after lone travelers, and those who have been chased say they feel an intense cold and fear.

The scariest mummy ghost story I know is about a mummy that was found in a hidden tomb. When a young explorer found it, he took a small relic from the mummy.

In my hometown, there's a story of a mansion that was haunted. The family that used to live there all died mysteriously. People who passed by at night said they could see flickering lights inside the empty mansion as if someone was still living there. They also claimed to hear screams and cries coming from within. It was so terrifying that no one wanted to go near the place. The story goes that the family had made a deal with the devil, and this was their punishment.
