But I know that in one case, this may happen in Feng Shui:
Your house is dark, or the place where you live is partial.
If you turn off the lights after eleven o'clock at night and sit quietly with your eyes closed,
If you are afraid, it has something to do with Feng Shui.
This situation will affect children under 5 years old, and the greater the impact.
The smaller it is. But it affects adults.
