In the second synthesized sound, I also used multiple layers of synthesized sounds to overlay. This synthesizer sound is mainly to express the impact of car noise on sleep, I have recorded in the field during the middle of the night outside the sound, in the recording, I will hear the car rubbing the ground to make a loud sound. The presence of this sound in the residential area is to disturbs the sleep of residents.

I modulated a sound similar to that of a sports car rubbing the ground in the Alchemy and superimposed it twice, this represents the noise of this car that has been troubling people’s sleep.

In the other two synthesizer sounds, I also used multiple layers of synthesized sounds layered on top of each other. In these two sounds, I aimed to get the sound of the more eerie and scary atmosphere of my dream world.

In the third synth sound, I added two tracks of bass effects to give the whole thing a fullness. I also sampled the previously recorded police car siren and transposed it so that the originally harsh sound was transformed into a series of barking dogs. I played a loop with a sweeping bass, and the modulated bass sounded very much like the monster in my dream destroying my dream world. And at the end I added a little bit of heartbeat, representing my nightmare of being very nervous.

In the fourth synth sound, I also used a loop to create the tension of my nightmare. I used an electric guitar type synth sound as a main melody, which gave me a sense of energy and made me feel tense like my nightmare.
