I went to the mountain that I’ve been to before. I did filed recording from 10:30 a.m. to 12:30 p.m. in these two hours of recording, I can clearly hear the difference. Between 10:30 and 11:00, there are a lot of bird calls in the trees, and there are many kinds of birds singing. But at noon like start of 11:00, the bird calls gradually stopped, and there were only a few calls.

During the recording process, I also clearly heard the sound of some planes flying across the sky, about once every 10-15 minutes.

In the recording, the sound emitted by some objects, organisms and plants is very light, and the microphone can’t record it. For example, the sound of falling leaves, and during the recording, I saw a little wild cat jump out of the grass, but didn’t make any sound. I can see these pictures clearly, which is also similar to my dream. I can see the pictures but can’t hear the sound.

At about two o’clock in the afternoon, I went to another place in the mountains to record. That place was the same place as the place where I went before with the sound of water flow. Strangely, there seems to be no water in that place today. This also shows that the sound will be dynamic. The water is left from the top of the mountain, which means that there should be no water at the top of the mountain today. This is in great contrast to the previous scene.
