12 What are the ways to attract ghosts at midnight? Can you see what is around you?

This ghost is actually produced by a self-psychological test. For example, you just watched a ghost movie and then walked home. When you hear any sound, you will think of a ghost in your heart. This is actually a psychological test. But there is also a situation that China has many wonderful things. Let me give you an example: just a valley. It just thundered that day, and someone killed a man in that valley. From then on, every time it thundered, you could hear people screaming before they died. In fact, this can be explained by science. There is a magnetic distance in the valley rocks, and lightning makes it record the sound at that time. It's like the principle of tape.
