When we went to the beach to enjoy the joy of swimming, it was inevitable that the waves slap on the wind and even drown my head. When there was a huge wind rolling up the waves from my back. At that moment, I suddenly heard the sound of my eardrum bulging, and then the accompanying sound was a steady squeaky sound. This sound suddenly stops after around 5 seconds. It sounds like the  person on the TV who is playing the heartbeat machine has no heartbeat. This sound is like sending a meaning to my ear from my brain.

 

In the dark night, the moment what I was most afraid is when I turned off the lights and I ran to my bed. Although the eyes can adapt slowly to the dark environment, But the dark environment also brings more attention to listening. Sometimes I hear a squeaky voice on the bed, which sounds like an insect. But what is terrible is that the sound seems to happen outside the window, as it happens in my room. I am afraid that there may be an insect in my bedroom.

In addition, I also heard the sound like a sawtooth paw cutting a plastic bag in the darkness of the day, which is rhythmic and regular. The sound of the night is always horrible.
