Is the eerie mannequin performing a spiritualist ritual or just a prank?

The John Lawson House is considered one of the creepiest houses in the United States, because there are always several strange retail mannequins placed outside this uninhabited house, and it is said that these retail mannequins sometimes move by themselves, and even change their clothes and number, but no one has ever seen anyone move them, and no one knows who put them there.

Despite this, a common local belief is that the retail mannequins were placed there to perform some kind of spiritualist ritual—allowing the spirits of those who died in a tragic train accident to possess them.

In the winter of 1871, a tragic train accident occurred near the New Hamburg train station in New York. A train suddenly derailed and crashed into nearby houses, killing 22 people on the spot. The John Lawson House is located 200 meters away from the scene of the accident, and it is said that the retail mannequins are always facing the scene of the accident. The John Lawson House was built in 1845 and was the only house that survived the car accident. However, after the accident, the owner sold the house and moved away. Soon after the house was abandoned, people began to place dolls outside the house, until they later became retail mannequins. However, the strange thing is that no one knows who placed these retail mannequins, and no one knows what their purpose is; and what is even more creepy is that although no one lives in this house, the inside and the surroundings are often cleaned very cleanly, and even the courtyard of the house is full of flowers. The whole house looks like it is inhabited, but what people see are always lifeless retail mannequins.

Now the retail mannequins outside John Lawson's house have disappeared, but people still claim to see candles lit in the house at night, with several retail mannequins standing inside, only to find the house empty the next day. No one knows who the owner of the house is, nor does anyone know the purpose of placing these retail mannequins. Is this some kind of spiritualist ritual or a prank?
