Have you ever played the four-corner shoulder-tapping game? This is a ghost-drawing game.
Four people stand in the four corners of the room. The first person takes a picture of each person clockwise, and then the fourth person in turn.
If there is no one in the corner the fourth person goes to, knock on the wall.
My roommates and I played the four-corner game repeatedly in a room with no windows or doors.
My position happened to be the last one, and strangely, during the game, I felt two strong forces hitting me.
Moreover, the positions of my friends and I changed again and again, and no one could tell who would see the ghost first.
Intention: Friendship and family affection
