All around me there was orange. I thought I was going for an ordinary walk, but then, all of a sudden, I found myself in this place. The walls were orange, the light was orange, and the ceiling was orange. I cautiously took a few steps forward then walked slowly through the tunnel. The walkway was not orange, it was an ordinary sidewalk. I breathed in and smelled a familiar scent. Citrus perhaps? I brushed the wall of the tunnel with my hand, and at my touch, there was a sound. Not exactly what I would have expected, not the sound of a hand brushing up against a sheetrock or cement wall, and not what might have been thought of as a pretty sound, like a harp or perhaps a harmonica, either. The sound I heard was of a series of PVC pipes - hanging vertically - being bumped into each other and making a hollow plastic-y sound. At first, I was confused. What kind of a tunnel was this? Why did it make this sound? I brushed the wall again. I heard the very same sound, but this time I listened more closely. All the pipes had a slightly different tone and the resulting sound reminded me of a wind chime. As the pipes touched each other and swung back and forth, I heard this sound as music. Who knew that plastic pipes could bring music to a person’s ears? I ran my fingers along the walls of the tunnel and kept walking.
