What does the fortune teller mean by pouring some water at the bedside and at the door at night?

The fortune teller said that pouring some water at the door of the bed at night is to prevent ghosts from pressing the bed after coming out at night. Pour water because it can make the humidity of the room bigger, make the ghost unable to walk, make the body heavier, and avoid going to the bedside to ensure your sleep quality and health. This answer is for reference only, don't be blindly superstitious.
