What is often called Descartes' dream problem (‘How do I know that I am not now dreaming?’) should perhaps be called Plato's dream problem instead. Certainly it can be found in Plato's Theaetetus at 158b–c. It can also be found in Cicero (Academica 2.27.88) and, through Cicero's influence, in much of the work of St Augustine.
