Do you believe there are ghosts in the world?
I believe this world exists. There are some things that science cannot explain. In the past, when the flow of people was not so concentrated, you could often see some things that were not consistent with common sense.
For example, it would be fine if you walked to the river, but ropes, silk scarves, etc. Come out of the water... Then you have to ask the famous village goddess to invite them away.
