Updated information of the interaction

Now I have the starting point as a dream. In that dream, I travel to different places, but with those little things such as keys, rings together. Now the interaction will be scrolling around and if your current location is very near to one of the 3 places in my dream, you can hear the sound I made for that area. When you gradually leave that region, the volume will be lower. So the main point of my project right now is to mix the sounds and make them distinguishable with each other so that viewers can easily remember these 3 places.
