Noisy Voices lyrics

I can't hear you voice but i can see your lips move That's because we are missing the invisible All those things that i can't touch nor see Make me wonder what is this world i feel All those noises, and all those voices i can hear Are they real, as real as me? Are these machine voices as real as those in thoughts? Is the sound a mechanical power or a sensation? There are many things around me that i can't notice Limited senses show me this narrow part of truth
