Matan is an Israeli soldier who went inside one of the Hamas tunnels in the Gaza Strip during the 2014 Israeli attack against Gaza.
He has been suffering from a very severe psychological shock since then.
His family has been trying to treat him and help him get out of the tunnel that he has not managed to get out of it, mentally, yet.
His family says he always suffers from seizures and is surrounded by illusions, whenever a plane passes through their airspace, as if he is still taking part in one of Shejaiya battles.
This is obviously Matan's guilty conscience of the atrocities that he has been involved in on the people of Gaza
