Le garçon lumière

LUCIE has this recurring dream where she falls deeper and deeper, into a never ending vacuum, as if irresistibly drawn by a blinding star. When she's awake she sees lights flashing in her field of vision, altering her conscience. Her parents are worried. Doctors try to find an explanation and a cure. Where does this most shining star comes from? What obscure corner of our life do these flashes try to shed light on so insistently?
