What can a living dead man dream about?

Mamuka: The only thing that makes me different from the dead - they lie in the cold ground, and I have been lying in my old bed for over 20 years, in this cold room, where no one cares about me. If it wasn't for my old mother, I wouldn't even have anyone to serve me water. There is no one! 

My father and two brothers died, and I didn't have a wife or children - I didn't manage to start a family.So, my mother and I were left alone. The only thing I dream about, so that I don't feel like a corpse, is communicating either with people on the phone or through a TV screen. Unfortunately, I don't have a phone, and the TV is at its last gasp.If it completely breaks down, it will be hard for me to distinguish whether I am alive.
