Noisy voices

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
