' Ring that bell '...
While the dream is still continuing, he cannot help taking its scenes and figures as being quite real.
But if someone rings a bell until he awakens from the dreaming state, he will then see that both scenes and figures were mere figments of his own imagination.
In a sense, the teacher of philosophy acts as this awakener did, except that he directs his efforts to the sense-deceived consciousness of everyday life.
