ghost

Ghost is an imaginary character that some people believe exists in the form of an invisible being who can float or travel through walls. It is believed that some ghosts are the spirits of people who have died, while others are simply supernatural beings that can be seen or heard in certain places. Ghosts are often said to appear in places with a lot of emotional or historical significance. People may report having a ghostly encounter if they feel a presence in a room or hear strange noises. People may also report seeing a ghostly figure out of the corner of their eye or feeling an icy chill in the air.
