Why is the house that hasn't lived for a long time overgrown with weeds and heavy yin?

As for the houses where people used to live, because people often live, the sun is very strong, and generally some ghosts and gods will not disturb them. But if it is an empty city that has been uninhabited for a long time, there may be some legendary ghosts living there. The performance of heavy yin is obvious, that is, inner discomfort, chills all over, goose bumps, maybe a little scared, and even a little dizzy (a friend with strong sensing ability). This situation will be alleviated if several people are together. Then there are some monsters in it.

Of course, there is also a scientific explanation. For example, because people live in the past, they leave clues about human activities and so on, so that the brain can supplement people's perceptual thinking, but there is a lot of evidence to prove that no one's rational thinking conflicts, so I think some monsters may be at work and some people are nervous.
